Hi...Your problem doesn't sound unusual. Sometimes preganancy causes the uterine lining to become thickened. You might want to talk to your doctor about a D & C procedure, in which he will scrape out the thickened endometrial lining. If you are not planning any more pregnancies, you might want to also talk to him about the Thermachoice Endometrial Ablation, in which the endometrial lining is destroyed by a heated balloon and monthly periods are VERY light to no bleeding at all. Good luck....Kim, RN, BSN, GYN Team leader.
