Hi, My wife has like 1.5 cm cyst in ovary. Previously she undergone surgery to get rid of the cyst, but it recurred. The cyst is stable and not growing for last 6-7 years and its benign. Now, we are planning to go on a trip and she needs to delay period for 8-10 days. My relative who is a general physician prescribed norethisterone 5mg tds for 2 week, starting 3-4 days before expected date of period. My question is, does norethisterone have negative effect on ovarian cyst? Is this safe to take? My relaative who prescribed the drug wanted us to discuss with a gynaecologist. So here i am.
