Hello, I am 22 years old and was diagnosed with endometriosis August 2013. My gynaecologist told me to take my pill 3 months at a time, meaning I only have four periods a year in a hope to reduce the rate it comes back after having a majority of it removed. Since then I have had no problems aside from a slightly heavier and more painful period. I had my period just over 2 weeks ago like normal and began my pill as usual. It was slightly more painful than usual, but it seems to hurt a little more each time. However yesterday I started to have some stomach cramps and noticed a small amount of very dark brown discharge, which is still there again today. I read that during the time you ovulate your body can shed the old blood which did not fully leave last time (which is often a dark brown). I know with my last period in particular it was quite heavy and only stopped because I re-started my pill. I was just wondering if anyone has experienced this before or it seems normal as this is the first time it has happened to me. And also if it will stop in a couple of days after ovulation stops.
