Has anyone ever tried using an OPK to test for early pregnancy? I know it sounds crazy, but I have read that they can pick up early traces of pregnancy. I thought I would try it b/c I keep getting vvvfl on PT, the last time I checked an OPK it came up completely negative after my positive results, so I know it's not just giving false negs, just tried this & it for sure gave me two lines I think. what do you guys think? And btw I am 12 DPO today.
