Good afternoon. I am 42 years old. I had an endometrial ablation 10 years ago. Since my ablation, I have regular periods. Bleeding is light the first day then more "regular" on the 2-4th day. Light for last 2 days. So, total of 6 days bleeding. I have just found out that I am almost 6 weeks pregnant. I've had no break through bleeding, no nausea, but have had some mild low back pain and very mild uterine cramping. My question is... having had the ablation, will I be able to sustain a pregnancy? Does the lining grow back over time? I am very worried about losing the baby. The baby is very much wanted. This is my first pregnancy. I had a sonogram in August due to a problem with my IUD. It showed my uterine lining to be .5. I don't know if that is .5mm or .5 inches??? I would assume at .5mm, implantation probably could not occur, correct? Please offer your advice and expertise. Thank you.
