Ok, so I have posted quite a few of these the last couple days but it's just because I need some answers and I just found the site yesterday lol. Any ways, I have been on metformin for 7 months and have been getting my period every 28 days regularly. Seems to be working very well... however this month I am 4 days late and I have been just spotting a little for the last 2 weeks. My husband was away for work last month during the time I was ovulating so I wouldn't have gotten pregnant last month. Is it possible that I got pregnant the month before and just had one last period. The thing about it is, I took a PT and I got 1 neg and 1 pos??? My mom said just to wait a little while longer and see if I start. Any comments? I hate it when you get your hopes up and then get shot down with that big fat negitive so is this wierd to anyone else or does that seem normal? I know other things can delay your period I just keep thinking to myself when the heck is it going to come? I don't even have cramps like I am going to start and I usually do. I am just having some light spotting, PLEASE HELP. I want to know I'm not being just crazy.
