I had surgery on the 21st April and the day of surgery I got my period and it's been heavy then light then a few days of like black mucus then milky, then a couple days nothing and then it will be heavy again its been like this for 4 weeks now... I also have PCOS and very unregular periods. like I miss them for months at a time but this is the longest I've had them for... has anyone else experienced this after surgery?
