The question that lurks in the mind of many women who are trying to conceive is when to take a pregnancy test. If you have been trying hard to conceive and have started to observe some potential pregnancy signs like a headache, nausea, and fatigue then you may not be able to resist doing a pregnancy test at home.
But when should you do a pregnancy test? Can pregnancy be detected in a week or should you wait until the first day you miss your periods?
Is it possible to detect pregnancy in a week?
You definitely can do a pregnancy test within a week of ovulation and no one is stopping you from that. But the question that arises is whether taking a test so early could give you the correct result?
The pregnancy test should not be taken before 8 days past ovulation. This is because if you take a pregnancy test quicker than that then you may not get the correct result. The reason for this is that the implantation does not occur and even if the conception has happened. The fertilized egg is still to start producing hCG which is the hormone that detects pregnancy. The hCG gets produced only once the implantation is complete.
Taking a pregnancy test early can give you wrong results
Implantation can happen 6 to 12 days after ovulation but in the maximum cases, it happens only after 8 days and 10 days after ovulation.
Even if implantation does happen at the 6th day the hCG levels start to double only around 48 hours post implantation. The hCG levels at early-pregnancy and the doubling of hCG vary from one pregnancy to another. All these determine when the pregnancy test will show the actual result.
There are very high chances of a wrong result if you take the pregnancy test within one week of ovulation. You need to give time for the implantation to occur and the hCG levels to build up to be able to do a pregnancy test and this takes more than a weeks’ time.
A pregnancy test detects the hCG hormone in the urine or blood to know if the woman is pregnant. You thus need to give time for this to be able to take the pregnancy test. There are very bleak chances that pregnancy is detected in a week.
The amount of hCG in the system will be around 25 mIU at 10 days past ovulation, 50 mIU around 12 days past ovulation and 100 mIU at roughly two weeks past ovulation. This means that you should begin testing for your pregnancy, not before8-10 days past ovulation. If you do a test early and the result is negative then you should not rule out the possibility of being pregnant. You should do it again post 10 days to confirm your pregnancy.
