Losing hope

7 years with my husband, 6 miscarriages and 2 blighted ovums. Furthest along we got is 10 weeks. Usually miscarry between 6-8 weeks. We dont have any biological children together. We both got tested, there's nothing wrong. I had an ectopic pregnancy in the past and had my right fallopian tube and ovary removed. It seems I can get pregnant sometimes, but cant carry. I'm 36 now and starting to lose hope. I see my friends having kids still and I would love to have one more. My breasts have been sore for 10 days, yesterday and today have been terrible. According to my Misfit (tracks my steps and sleep), I have been sleeping 10-12 hrs each day. I usually only sleep 6-8 at the most. I had cramping about 5 days ago. AF is supposed to be here tomorrow. Just expecting another BFN. Any tips to help us out?
