<s>[INST] doctors removed my chocolate cyst in both ovaries last year that was about 7cm and 3cm each.know i am taking duphaston and lyglow 3 months course.what are the chances of conception [/INST] HelloThanks for your query. I will try my best to provide you with the best possible professional recommendations to your questions. DO Not attempt to get pregnant for these 3 months! The injection is intended to shrink the endometriosis, by concentrated hormones, so AFTER you will be more likely to become pregnant. It is unlikely you would have your period while these injections are ongoing. Try to avoid unprotected sex during the course of treatment. Yet again, I do hope that you have found something helpful, and I will be glad to answer any further query. Regards </s>
