Help!

My husband and I have been TTC for 9 months. 3 weeks ago I was prescribed with 10 days of provera, also started metformin.(due to absent cycles)  The day after finishing provera my Period started, lasted 6 days. Two days after my period had stopped completely I have started having a peachy pink spotting for 2ish days now, it's only when I wipe. (I'm still on metformin 1500mg) Any ideas??
