Hello all! Looking for some insight. I had a polyp removed along with a D&C on 8/7/18. My last LMP was 7/28/18-8/3/18. Tomorrow 9/4/18 makes 4 weeks post d&c. I DTD on 8/16,24,31. I've been having back pains, mild cramping, sore boobs, bloating, etc....all pms symptoms that have been coming and going. Only difference is i feel my boobs more achy and heavy than usual..not one of my normal symptoms. This might be a new pms symptom?🙍. Does a D&C change your cycle? If so when should I expect my next menstral cycle? How long should I wait to try a hpt? Any insight will be appreciated.
