Okay ladies I know i have asked before. I kno that metformin will mess with ur period. I was just recently upped on the amount that I take. I went from 500 to 850. But my think is how n the world would u start ur period right after u get done ovulating. But technically according to glow I was still suppose to be ovulating today as well. But instead I woke up from a nap with AF showing up. But I did have unprotected sex during my ovulation period though. Do u think it could be my period or implantion bleeding. I'm really confused.
