I was diagnosed with two chocolate cyst, one in right ovary (1.8cm) and 1 in left (2.3cm). Doctor told me it is endometriosis and prescribed me rumigest for 3 months. I never had pelvic pain or any other symptoms except for delay of 4-5 days in my cycle. The 1st month with rumigest was fine. I had almost very little periods. In the second month i had periods for10 days And i took medicine to stop bleeding, it stopped. Now again in 3rd month i had been bleeding for 15 days. Why is this happening?
