I have had multiple sonograms over the past few months and every time I have a thick lining that never seems to thin out like it should. This can cause cancer if it is not addressed or determined what the issue is, but my doctor's can't seem to figure out what the issue is. They did put me on a low estrogen birth control pill and I have had a D&C done, but neither really helped.
I had the same issue. They couldn’t figure out why and decided to do surgery to see what the issue was. I had polyps. They removed them all and for what seems the first time in forever I have normal cycles. I just take other supplements to try to keep them regular. That was the only answer I received. So far no other issues though.
