Based on what you read, can you use opk as a pregnancy test? I went to the doc yd and he confirmed o with the release of an egg not just a surge. So if I take an opk say at 5 or 10 dpo and I have a pos opk then does that mean I'm pg Bc my Lh is at 0 now. I watched it go to 0 with opk. I haven't done the opks after my Lh surge and 0 levels to see if they did go up, cause I'm 3 dpo.but I might just to see if it's true. Anyone do this?
