7 DPO – Know Your Chances Of Becoming Pregnant

7 DPO‘7 DPO’ or seven days post ovulation falls in the marginal region where the implantation happens. Knowing the possible time frame of becoming pregnant is very important for women. In the recent series on 13 DPO, 9, and 12 DPO and 4 DPO, this article focuses on 7 DPO.

What Happens During 7 DPO?

Ovaries release the ovum; the mature egg is ready to meet and fertilize the sperm in the fallopian tube. The dropped egg then moves towards your uterus via the fallopian tube. The viable sperm meets the egg in the fallopian tube, and once they meet up, the sperm fertilizes the egg to form the zygote, which moves towards the uterus and implants into the uterine wall. During this period, the zygote multiplies its cell count and grows as an embryo. Meanwhile, the wall of the uterus also prepares bedding with a rich blood supply to receive the zygote. Since this travel happens through the first 4-6 days, there is a narrow chance to make sure about your pregnancy seven days post ovulation.

However, if the ovum failed to meet the sperm or if fertilization did not happen, the uterine wall will start to shed off. This shedding of the uterine layer is what you experience as menstruation. Menstruation takes place in cycles, and the duration of the cycle differs between women. Ovulation would occur anywhere between 11 to 21 days of your menstrual cycle, and it depends on the average duration of your menstrual cycle. These events are under the guidance of female reproductive hormones – estrogen and progesterone.

Estrogen

The ovaries secrete estrogen, which is the female reproductive hormone. Estriol is a common type of estrogen which is predominant during pregnancy. Estrogen controls the growth of the uterine lining called the endometrium. If no fertilization happens, estrogen levels drop abruptly, leading to the endometrium’s shedding. Subsequently, menstruation occurs. In the case of fertilization, estrogen joins hands with another sex hormone, progesterone. The duo maintains the pregnancy and stops ovulation during pregnancy. Estrogen is also responsible for females’ secondary sexual characteristics, such as breasts, wider hips, pubic hair, and armpit hair.

Progesterone

Progesterone is the other primary sex hormone, regulating menstruation and supporting pregnancy. A part of the ovary, adrenal glands, and placenta produce progesterone. When fertilization takes place, progesterone prepares the uterus to hold the pregnancy. It stimulates the development of glandular tissue and new blood vessels in the uterus. In the absence of fertilization, the endometrium sheds down, and menstruation begins.

Human Chorionic Gonadotropin (hCG)

With the implantation of the zygote in the uterine cavity, a rise in human chorionic gonadotropin (hCG) levels begins. Levels of hCG differ between individuals, so as the symptoms. If at all these symptoms occur, they are usually identical to those of your perimenstrual symptoms. Tracking your menstruation would help you identify those symptoms and distinguish whether they are related to pregnancy or your periods.

Usually, the signs are indicators of altered hormonal levels in the blood. The hormone levels differ between individuals, and the symptoms vary. Similarly, the 7 DPO symptoms are infrequent and different too. Since the implantation occurs between 6 DPO – 8 DPO and hCG does not go up immediately after implantation, having pregnancy symptoms by 7 DPO is less, compared to 9 DPO, 12 DPO, or 13 DPO.

Symptoms at 7 DPO

The followings are the symptoms of pregnancy you might experience.Symptom checker sample

Cramps

You might get cramps during the 7 DPO, those are similar to the cramps that occur during your periods. You would feel the pangs in your lower abdomen, but cramps are not specific and unreliable evidence of pregnancy.

Spotting or Bleeding

The spotting usually occurs after the implantation of the embryo. The reason behind this is the tissue shedding in the uterus when the fertilized egg gets implanted. But this ‘implantation spotting’ can occur 7 to 12 days following fertilization, which might coincide with the dates of your next period. Since it might last for 2 or 3 days, you might get confused with menstruation despite the amount and characteristics of bleeding. So, in 7 DPO, it is likely to have these symptoms since the fertilized ovum gets implanted in the uterine wall during this time.

Nausea

Nausea is a famous symptom of pregnancy. A substantial rise of hCG following implantation doubles up hCG levels every 48 hours to cause nausea. Nausea striking due to the pregnancy is called morning sickness, but it can occur at any time of the day. Higher levels of hCG usually result in more nausea. But this symptom will go away by the 13 – 14 weeks of your pregnancy. Since the hCG rise significantly enough to create an imbalance, nausea might not set in by 7 DPO.

Vaginal Discharge

Apart from bleeding or spotting, you may notice a whitish discharge from the vagina. The implantation results in changes in vaginal walls. Subsequent changes in vaginal wall thickening result in this discharge. However, it is not harmful and doesn’t need treatment. But, in case if you feel having a bad smell or itching or burning sensation related to the discharge, it is always advisable to seek medical attention to rule out bacterial or yeast infections. This secretion might continue throughout your pregnancy.

Fatigue

Fatigue is another common symptom experienced by many pregnant women. Subsequent to the implantation, the progesterone level also increases. Even though progesterone is an important hormone to maintain the pregnancy, an increased level of progesterone can be linked to fatigue that you experience.

On the other hand, changes take place in the blood supply to the uterus. In turn, this affects the circulatory system of the body. Similarly, the low sugar level also might cause fatigue. Ultimately, an increase in the demand for sugar, oxygen, and changes in the circulatory system make you feel tired.

Eating foods rich in iron and protein, drinking an adequate amount of water to stay hydrated, and taking rest can help you relieved pregnancy-related fatigue.

Changes in Breasts

The female reproductive hormones, estrogen, and progesterone influence the breasts just like they control ovaries. Increasing levels of progesterone affect the breasts. Hence, changes in the breast changes are appreciable during the initial days of pregnancy.

Your breast becomes more prominent, and your nipples and areola (the dark pigmented area around the nipples) also start to turn darker. Your breasts will start becoming more sensitive. They will be tender to touch. When the pregnancy progresses, these symptoms disappear. But by 7 DPO, if your ovum is not implanted, you will not have any significant changes in the hormonal levels. Subsequently, changes in breasts also might not become significant.

Food Cravings

Usually, your preferences towards specific food change due to hormonal changes. You may start to crave certain foods, flavors, or smells. On the other hand, you might begin disliking or avoid certain food items or fragrances. Common food cravings are sweets, salty food, spicy food, citric food, chocolates, coffee, and ice cream.

Even though we do not have a clear explanation for this alteration, it may relate to the nutritional status. Pregnancy increases the demand for the nutrients like minerals and vitamins, subsequently resulting in the craving for specific foods. Meanwhile, the female reproductive hormones, namely estrogen, and progesterone, are linked to these cravings by influencing the nervous system.

The good news – that this may not stay for the whole duration of your pregnancy! But again, 7 DPO might not a period where you would start craving or avoiding.

Pregnancy Test at 7 DPO

The pregnancy test kits are the most common tool used by women to diagnose pregnancy. (R) They detect the presence of hCG in the urine using antibodies. These test kits are available over the counter worldwide, with ‘over 99%’ of accuracy, claimed by the manufacturers. Since the pregnancy test kits’ sensitivity differ, always read the information leaflet that comes with the test kit.

How to test?

Different test kits require different methods of testing urine hCG. Thoroughly go through the instructions that come with the kit. Some test sticks would require you to pee on the test stick, while some need to be put in your urine that is collected in a cup or container.

How are the results shown?

Like the way you test, the way those strips show the result might differ between each kit. Few methods to show the result show color lines (pink or blue), plus and minus signs, or changes in urine color. Some digital kits say pregnant or not pregnant and show you an estimated time since your conception in weeks.

The above information is related to the regular pregnancy checks and probably after 9DPO. The hormone hCG appears in the blood 9-10 days after conception and doubles daily to reach a steady level in 45 days. The urine hCG test depends on the concentration of hCG in your urine. Performing a trial in the early morning of your next period would be better to get a reliable result since your urine gets concentrated overnight.

Even though these home pregnancy kits give straightforward results, there is a possibility of getting false positives and false negatives. False-positive is nothing, but your kit would say you are pregnant, but in reality, you are not. Similarly, a false negative is when you are pregnant, and your test kit does not show a positive.

These false positives and false negatives might be confusing, so visit your physician if at all you are in doubt. Read further to understand more about the false negative.

Is 7 DPO BFP Possible?

Big fat positive (BFP) by 7 DPO is highly unlikely. Firstly, remember the duration between the possible implantation and 7 DPO is short of strong evidence predicting the possibility of a pregnancy. Since there is a chance that the ovum might have been fertilized by the sperm and still in transit towards the uterus, you may not get positive results too. Hence, the sequence of effects usually occurring after implantation in pregnancy is improbable.

Let’s do a recap to understand why it may be negative. In a regularly menstruating woman, after intercourse, the sperm fertilizes the ovum to form the embryo, and it implants in 6 – 12 days. It can even delay as long as 15 days. A particular hormone level, human chorionic gonadotropin (hCG), produces a positive result while using the pregnancy kits. This is a hormone usually produced about 2 – 5 days following the implantation. Considering this time frame, detecting hCG in your blood or urine might differ. Hence, the pregnancy test on your 7 DPO may not be positive.

Even if it’s the most preferred day to test pregnancy is 13 DPO, you might not get a positive result in the urine hCG test. That doesn’t mean that you are not pregnant. Usually, if you test 7 DPO, it is highly likely to have negative results since the implantation and related hormonal changes are not yet present. Hence BFP in 7 DPO is unlikely; however, having a negative pregnancy test does not mean there is no pregnancy for sure. Do not lose hope till you see a BFP at 13 DPO or get your pregnancy confirmed by your physician.

No Symptoms

Most of the time, you will not experience symptoms by 7 DPO. Menstrual cycles are unique for each woman. Similarly, the symptoms also differ in time and intensity. These different times explain the variation of pregnancy signs. Meanwhile, there are instances where no pregnancy symptoms are experienced even at 9, 12, or 13 DPO. It does not necessarily mean that you did not conceive. If you have irregular menstrual cycles, then the ovulation might have happened later than usual. Consequently, the symptoms also get delayed. Using a symptom log like a CareClinic app would be beneficial to track your symptoms.

Also, the symptoms you feel in pregnancy may not be present in another pregnancy. Hence, it is nothing surprising even if you do not experience any symptoms at all.

In conclusion, do not worry if you do not experience any of these symptoms. There may be chances of getting a positive result in urine hCG but not definitely by 7 DPO. Hence, do the pregnancy test at 13 DPO and repeat the test in a few days to confirm the outcome.

Despite the presence or absence of symptoms at 7 DPO, always go for a 13 DPO pregnancy test to confirm the status. Apart from all of these, if you have any concerns about your health, reach out to your physician. Especially when you experience unpleasant symptoms, please consult your physician.
