I've been on metformin for two months now. I needed to take progesterone to start AF the first month and I had a feeling that I would need it again to start it up this month as well. So I took it. I took all 10 pills and still nothing (it's been 5 days sense my last progesterone). I spotted lightly three days ago. Yesterday, what i assumed was AF, bleed a little bit. And today I spotted less then day one, but it's brown.. tmi.

So my question is, wtf is going on!?

I've done progesterone & metformin in the past, did it for 6 months and it will ALWAYS start it by the 5th pill. Never had an issue.

Is it possible to not have one because of possible pregnancy even though I'm taking meds to force af to start??
