I have been having prolonged bleeding lasting 3-4 weeks at a time since having had a D&C in late March. This bleeding is accompanied by outbreaks of shingles. The only time the bleeding stops is 2 weeks into a new birth control. My doctor has run blood tests for hormones and thyroid, ultrasounds, pelvic exams, and pap-smears. All results have come back normal. My OBGYN says it s a weight issue. I am 31 years old, 5 10 and 230 lbs. I have been this weight since the birth of my first child 8 years ago, and have not had any problems prior to the D&C. Is he right that simply losing weight will help, or is there something else that could be causing all this that we are missing?
