I’ve been in metformin for 5 days before I started my period, I haven’t had my period in 3 months before this and my period lasted about 14 days, could I have ovulated? I took Ovulation tests and the first one I took half of the line was dark and full but not good enough for passing and I waited 2 days and it was no LH surge so maybe I just just ovulated and missed it a little bit? also why did I have my period for 14 days it was really really light only needed to wear a panty liner
