First cycle on Metformin

Stephanie • Just some newlyweds trying to conceive our first baby!!🤗👩🏻👨🏻👶🏼

Hey ladies this is my first cycle on metformin and so far I think it’s working great! I got my positive OPK on cycle day 17( a week ago today) earlier then the app predicted, but I just knew i was ovulating, I had extremely sore bbs the the day before ovulation and still today. Then today I have some light brownish discharge and mild cramping. Could it be implantation bleeding? 🤞🏻🤞🏻🤞🏻 this is my month I feel pregnant already!!
