In October 2013 I had the merina coil fitted due to my cycle being very heavy and all over the place. It was great for a while but the last two or three months I starting getting normal periods again. The last 8 weeks they last up to a week and a half, not heavy but constant. With two weeks they are back. I finished my period on the 27th of Jan and yesterday when I wipe after using toilet I have a brown discharge. I've never seen this before! Can anyone tell me what's going on? I've no pain or anything like that!
