I was diagnosed with endometriosis 2 Years back where I had to undergo surgery due to its severity. The cysts came back after a 4 months and I am on Endosis tablet from past 1 year, doctor has asked me to continue for 6 more months. Last month I missed the dose of Endosis for 2 days due to unforeseen circumstance and since then I have gotten my periods thrice in one month with moderate bleeding. I had restarted my dosage after 2 days still getting periods, is it normal ? By when can I expect the periods to stop with medicine effect ?
