I have been taking metformin 850mg 2 doses. Thyroid 50mg. My thyroid is normal now. I took regestrone 5mg 2 doses on 29 and 30th day for my cycle. I have irregular periods. But even after 10 days I did not get my periods. So I tried taking regestrone again on 40 and 41st day. I started bleeding on 41st day morning. My pregnancy tests showed negative. I have occasional pains in my vagina, sometimes feel constipated. What should I do?
