I dont trust the opk's either. I'm cramping for the last two days now too If my cycle wasn't messed up I should be gettin AF right around now. But again I haven't been feeling good at all Like i'm going to throw up (sorry TMI). OH keeps telling me to take a preg test but I"m like my cycle is screwed up and Dr said last week it looked like AF. but again it was not full blown like he said it would become. SO I have no clue what I should do! Do I wait another 2 weeks to see if I get af from the 2nd time I had it or do I take a preg test. I guess I just dont want to waste the money if its neg and get my hopes up. what do you girls think
