P.D.
I had the same problem. After having my second child it started happening. Doctor really never did anything about it till I had my third child. When my third child was two my doctor did a DNC and told me I need a hystrectomy. At that time I went for a second opinion and was put on a low dosage of birth control. The problem improve greatly and I even lost 12 pounds. I felt so much better. He told me it was a hormonal problem and not to worry. I have been on for 13 years. I spot sometimes but not a big deal and I can deal with so much more. I would go to the doctor and see what they say and I would try the birth control. If you don't feel like they help you can easily get off them. I really won't worry. I hope everything works out.
