HI! I had my left ovary and fallopian tube removed on April 23rd due to a 7cm mature ovarian teratoma. I had begun my period the night before surgery which would make the next one due 6 days ago. I feel pms'y..bloated, crampy, irritable, just like I'm getting my period but nothing. I'm feeling disappointed that my other ovary hasn't taken up the slack of the missing one yet. I've always been very regular, even with my tumor. Anyone have a similar surgery? Any insight into what to expect from my menstrual cycle?
