Metformin and irregular flo

다롱

my last flo jan 18-23 then some bleeding feb 13 and 14 followed by Randall pelvic pains. I work out every day lift/cardio but still no flo. I’ve tested 2 times and BFN. We’re going over seas in a month and I wanted to be preggo before that. I took metformin for flo in January should I test before I leave and just take the metformin when back? right now 10 days late if I was actually regular. Any advice?
