Hi, So I have irregular vaginal bleeding for a very long time. I was diagnosed with uterine polyps and also had undergone a surgery for the polyp removal and ovarian drilling for PCOS. Post surgery after a month I started bleeding again and that bleeding continued for 35 days abd then stopped for 7 days abd then continued for 28 days and stopped for 20 days and then continued till the time I was asked to have regesterone CR10 tablet fot 20 days. For first 10 days bleeding stopped but on Day 11 I started bleeding again. What could be the reason behind the bleeding?
