I havent had a period since my d&c following miscarraige back 4-16-08. I am only 22. The doctor had an ultrasound done, it came back with my endometrial lining measuring 9mm. When I questioned the results on what they mean, I was given the answer: " If it was 10mm I would be worried but its only 9mm so its fine." I am seriously freaking out wondering what it would mean if that TINY 1mm diference was there. I would go get another opinion but my insurance wont pay for any other doctor than the one I went to. Any advice?
