I have PCOS. My md said I’d never get pregnant without medical intervention. My husband and I are fine with that. We don’t use protection and if something happens it happens. If it doesn’t it doesn’t. Well

I’ve been on metformin for almost a year. This month is the third month in a row AF was on time for my 31 day cycles... or so I thought. I had the typical dark brown spotting, this went on for three days and on the third day, yesterday... bright red for one wipe. Now nothing. Am I nuts or is there a faint line on this test?
