Pcos,normal weight,baby born 2018,breastfed until mid2019,never got period back,but light bleeding now and then.gyn said in nov2019 that uterus looked fine,but thick endometrium.pap-smear=fine.no infection.provera didnt help.now constant bleed. why?

Delivery normal?: Was there any hemorrhaging during delivery? If so, this can cause a necrosis of the pituitary gland (Sheehan’s syndrome.). Make sure your doctor checks your levels of estradiol, LH and TSH. Also check prolactin levels because a pituitary adenoma which elevates prolactin can also cause amenorrhea. That said, I have seen normal patients who have not had a period in return for close to a year.
