Alright, I went without having a period for 5 months. I got put on Metformin, but stopped taking it once I started to bleed again. I bled for about 3 weeks, maybe 4 or 5 I can't exactly remember. Then I didn't bleed for 1 week. Then I started again and have been bleeding for 2-3 weeks again. Now I am having pretty strong cramps and its pretty painful. What should I do?? Is it time to call my doctor again??

** Just went to the restroom and now I have clots and a severe headache.
