I got a postive OPK and 3 days later had another positive, but take that as maybe I ovulated 2x.
The last 2 days OPKS were negative as were pregnancy tests. from what I've learned it does take a while to get positive OPKS if your actually pregnant. You'll get a positive pregnancy test before that.
It DOES detect HCG...well sort of. you can look at peeonastick.com to find out the whole scientific method of how that works. I got + opk after being further along in my pregnancy but not at the beginning. But if i pee on one now it comes up very positive.
I thought that the testing positive during pregnancy thing was a myth and tried it anyhow after a positive from the doctors office. It was negative. I had several left though because I bought a 30 pack and decided to take one about 1-2 weeks later and it was screaming positive. It does not detect HCG but your LH levels can rise again while pregnant and that is what it detects. I can tell you first hand that it can go positive after the positive pregnancy test, but I would not suspect before you get the positive pregnancy test. I would be more inclines to think that you are about to ovulate...keep trying and good luck!
Hi,
OPKs detect the LH surge which happens 24-48hrs before ovultion it doesnt detect HCG so i dont think its possible to detect pregnancy from OPKs.
It is possible that because you had you IUD removed its messed with your cycle.
Hope this helps
