By MomMed | 23 August 2022 | 0 Comments



The journey to getting pregnant is not easy. While some women get a positive just after a few tries, some have to wait long enough to see the magical, second line on the test strip. In the entire journey, what holds immense significance is the menstrual cycle. Tracking the different events, ovulation, fertility period, and changes in the body are crucial to succeeding in getting pregnant. Most women, with anxiety throbbing their heads, keep taking tests in the hope of getting a positive result. However, you do not become pregnant immediately after having unprotected sex. Even after fertilization, it takes a few days for your body to show that you are pregnant. Read the article to understand the process better with special highlights on what to expect from a 21 DPO pregnancy test.
 

Menstruation, Ovulation, and Pregnancy

If you have been trying to conceive then you most probably are acquainted with the term, DPO. if you are not, then we are here to clear it out for you. DPO stands for days post ovulation. Around the middle of every menstrual cycle, one of the ovaries releases a matured egg during ovulation. The egg then travels down the fallopian tube.
 
 If it happens to meet a sperm there, fertilization occurs, resulting in pregnancy. Usually, 5 days leading to ovulation and the day of ovulation are considered to be the most fertile days for a woman. It is commonly called the fertility window. Since the sperm can survive in the female body for 3-5 days and the egg remains viable just for 24 hours, having unprotected sex during these days enhances the chances of pregnancy.
 
However, in the absence of fertilization, the uterine lining sheds two weeks after ovulation. This causes menstrual bleeding.

 

What To Expect From a 21 DPO Pregnancy Test

If fertilization occurs post ovulation, then the zygote will divide to form an embryo on its way to the uterus. After about 8-12 days, the embryo will get implanted in the lining of the uterus. After implantation, a hormone called human chorionic gonadotropin gets released which helps to maintain the uterine lining. It is this hormone whose level is estimated to determine if you are pregnant or not.
 
At-home pregnancy tests will use antibodies to detect HCG in your urine. Immediately after implantation, only trace levels of Hcg are secreted. However, it shoots up during the first few weeks of pregnancy. In fact, it doubles up every 48 hours, for the first four weeks.
 
21 days post ovulation means that you are around 3 weeks of your pregnancy. Since the 21 DPO HCG levels can be high enough to be detected, a 21 DPO pregnancy test is most likely to give you a positive result, if conception has happened.
 

Things To Remember While Taking The Test

Most at-home pregnancy tests make pregnancy detection a cakewalk. It involves extremely simple steps like exposing a region of the test strip to urine for a few seconds and leaving it to dry.
 
On complete absorption, the result window displays the result in a few minutes. Based on the brands, the amount of time taken and the way in which the result is shown varies. Therefore, it is recommended to read the manual before taking the test.
 
The best time considered to take the test is morning. It is because the urine remains concentrated with Hcg during that time. With increasing fluid intake, the HCG in urine can get diluted and might result in a false negative.
 
Therefore, one of the reasons for a 21 DPO BFN ( Big Fat Negative) can be the dilution of HCG. However, this is a rare case, since your 21 DPO HCG levels are supposed to be too high to be diluted. In case, your hormone levels are not rising as fast as they should, this condition can happen.
 
Nevertheless, you can choose other times of the day to take the test. If you are doing so, then make sure to abstain from drinking water or urinating 4-6 hours prior to taking the test.
 

21 DPO Symptoms

At 21 weeks, you will most like have very frequent urges to visit empty your bladder. This happens because of more blood being sent to your kidneys. Other 21 DPO symptoms include nausea, vomiting, fatigue cravings for some food, and aversion to particular tastes and smells. Nausea and vomiting result from the surge of HCG. the term morning sickness used for that is a misnomer since it can occur at any time of the day. It is not necessary for all women to have all of these symptoms. You can either have a combination of a few of these or might just sail through your entire term without a symptom.
 

21 DPO Negative Pregnancy Result

It is true that it is unlikely to get a 21 DPO BFN. However, it is not impossible. Our bodies do not work the way we know them to work. There are variations in the timings and processes. The possibility of a 21 DPO negative pregnancy result can come from delayed ovulation. Otherwise, as discussed earlier, an insufficient spike in HCG due to ectopic pregnancy or other underlying causes can render its levels undetected by an at-home pregnancy test.
 
If you have not had your period yet and are having pregnancy symptoms despite a negative result, it might be indicative of a chemical pregnancy where you have undergone a very early miscarriage. In that case, you will most likely get your period in a few days.
 
Sometimes, a phantom pregnancy can lead to a negative result. In that condition, you experience all symptoms of pregnancy while you are actually not pregnant. However, before jumping to conclusions, it is better to visit your healthcare provider.
 

Conclusion

As per convention, a 21 DPO pregnancy test must give a positive result. However, everybody is different. Every pregnancy is unique. If you are hoping to conceive and have gotten a negative result 21 days post ovulation, then do not panic. A blood test and an ultrasound will confirm the case. If you are not pregnant, then keep calm. Do not let your hopes hit the bottom. You are just a few tries away!
