I'm 21, was diagnosed with pcos in November of last year. Right away my doc put me on Metformin 2 times a day 500mg. I haven't had a period yet, but (and I think I'm going crazy because of this) I keep getting this bizarre "fluttering" feeling in my belly, my sense of smell has been crazy intense, there is white discharge in my underwear (tmi...I know) but I've NEVER had that. It doesn't smell or anything. I've also noticed my chest looks and feels a little fuller and around my nipples has gotten darker. To top it all off I have not gotten a single positive test. It's driving me absolutely crazy. I do plan on making an appointment with my doc but I am wondering if anyone can relate? Can pcos maybe be why I can't get a positive test? Can someone explain this annoying fluttering?!
