Why would a pregnancy test turn positive 7 days past ovulation when not pregnant?

Question

The last two months I had home pregnancy tests turn positive (a very faint line) on 7th through 9th day past ovulation and then go back to negative. The first time around I had a blood test done that was negative. On all other times of the month my tests have been negative, but on those three days I have several positive ones, so I am not talking just one faulty test. Please answer only if you know what could be going on. Thanks!

Answer 1

Are you *sure* you know when you're ovulating? The most sensitive pregnancy test can usually *only* be positive 8 days after conception. How are you determining when you ovulate? Maybe you're ovulating a day or two earlier than you think?

There is no other hormone that mimics HCG in a pregnancy test. I assume you aren't taking HCG for any reason. You *may* be having early miscarriages. Failing that (or using the test incorrectly--seems unlikely if it's always and only happening on certain days), you need to see a doctor. It is probably indicative of a problem. But it is more likely to be an early miscarriage.

To be more certain of both of the above possibilities, I would suggest you chart your fertility signs (if you're not already). Please read _Taking Charge of Your Fertility_ by Toni Weschler.

Answer 2

That's called a chemical pregnancy. It's fairly common. That's the problem with testing too early. You should really only test one or two days before your missed period.

Answer 3

It could be that there ur hormones are unbalanced because of the timing.... the pregnancy test only looks for a few hormones but the blood work looks for all...

Answer 4

Id say its from the 17th as the ovulation test was positive. Yes its possible. Congratulations.
