Metformin experience?

Ashley • Hello all!I am 24,SO and I have been together for 4 and 1/2 years now.Just trying to get healthy&regulate AF so we can start TTC:) Fingers crossed!!
Anybody else have a weird start off?After AF for about 4weeks it finally stopped on its own.Started metformin to regulate on Jan 29th.I started my period the day before yesterday (Feb 9th) and that was it.one day period.now for two days I've just had the brownish discharge I usually get before my period just when I wipe,not even enough for a liner.can anybody relate?😧
