Confused & uncomfortable 😣

I need some help , I’m not sure what’s happening. I’m taking 500mg Metformin 2x a day and Gaia Vitex. Jan 18th- Jan 24th I had a period induced by provera. And I tested with opks to see if I ovulated (Ovulated CD 15-18) . Just this past week starting Feb 5-6th I started having faint pink discharge. An now I have cramps that come and go. But NO period 😱! I’m not sure what’s happening but I’m really uncomfortable. Has anyone experienced this???? Or something similar
