So I have periods every month, very light so my doctor put me on Metformin. Been on it now for 2months now. I stopped keeping track of my flow because I was giving up. But I remember last month Aug 18th for my son birthday party I thought to myself "I'm happy I didn't have it at the water park" because I was on my period lol.. So I can't recall if it started that day or a couple days before. Then before that I had one July 30th which went into the next month.. So I was mad cus I basically had two in one month. 3days ago went to the bathroom, very light pink when I wiped myself so I know it would start the next day or the day after cus that's what usually happens. Nothing happened, not spotting anymore. With my periods being weird idk if maybe im pregnant or my period will come later. Like I said I have them every month, may be early but I can't recall being late.
