Why do positive pregnancy tests fade




















Even if the line is faint, it is likely that pregnancy has occurred. Home pregnancy tests are a fairly accurate way to detect a pregnancy. Some tests are sensitive enough to detect a pregnancy up to 1 day after a missed period in some people. In this article, you can find answers to some of the common questions about faint positive lines on home pregnancy tests. There is a good chance that pregnancy did occur if a faint positive line appears on a home test.

Every pregnancy and pregnancy test is different. Some people have a noticeable dark line when they take a pregnancy test, while others notice more of a faint positive line. This is particularly true in early pregnancy when hormones levels are much lower.

Pregnancy tests measure levels of a hormone called human chorionic gonadotropin or hCG. The body produces more hCG after a fertilized egg implants in the wall of the womb. Some medicines contain hCG as an active ingredient , and so taking these can potentially lead to a false positive test result. Another possibility is a chemical pregnancy or very early miscarriage that occurs in the first 13 weeks after conception.

After a pregnancy loss, it takes some time for hCG levels to return to previous levels. Pregnancy tests measure hCG levels, and so taking a pregnancy test during this time will still give a positive result. Only a doctor can work out whether a faint positive result is due to early pregnancy, medication, or a chemical pregnancy. But, if a person gets a faint positive test result while they are bleeding, or they have a period, it may indicate a chemical pregnancy.

And towards the due date, hCG levels actually decrease. Two lines on our pregnancy test, no matter how faint, is a positive result. It could simply be that your urine was more diluted today, meaning it was harder for the test to detect the hCG. Test again in the morning when the hCG should be most concentrated.

If you test again over a few days or weeks and the line continues to get lighter or disappears, a couple of things could be happening:. Of course, you should reach out to your doctor if you have any concerns. Spotting aka implantation bleeding is much lighter than most periods and lasts for a day or two. Spotting happens when the fertilized egg causes a little bit of lining to detach during implantation and is an early sign of pregnancy.

Getting your full period after a positive pregnancy test, on the other hand, could potentially be a chemical pregnancy. A chemical pregnancy is a very early miscarriage that occurs when an egg is fertilized but does not fully implant into the uterus.

The bleeding associated with a chemical pregnancy is typically like a period, but can be heavier. If you test again and the result is negative, this could be the case.

If you are having a chemical pregnancy, keep this in mind: research shows that women may be more fertile following a chemical pregnancy. But sometimes, a pregnancy line disappears, and it could happen for a variety of reasons, Dr. Phillips in an email to Romper. Probably around three weeks after fertilization, What To Expect reported. So wait a little while longer so that you get the right result the first time. Another reason why your pregnancy test result changes seemingly overnight might have nothing to do with you, but rather the age of your exam.
