I'm supposed to get AF on Wednesday...how many of you have gotten positives 2 days before?? I've taken so many dang tests but it's hard to wait it out! I told myself after yesterday I was going to wait but then today I had some spotting which I've never had before! So it's like my excuse for testing again!
