I also had 5 m/c and then delivered a healthy baby boy 2 years ago, I was 41 at delivery. It's hard, but I made the decision that I wasn't going to give up. My RE told me it was just back luck and I was getting an old egg and that it would happen for me. I'm so glad I listed to him. Follow your dream, keep trying and it will happen for you too. Good luck and keep your faith.
I too had a rough time of it. 5 m/c, then a beautiful baby boy, and just recently another m/c. I have been asked so many times why I keep going and 'doing this to myself". It's because my desire to have children is stronger then the pain I suffer every time it doesn't work out. So for me, there is no other choice. Like you said, if I don't keep trying, then there is no possible way I will have another. For me, giving up is not an option.
I agree with happynifer...I would see a specialist. There is so much they can do now..women that in the past wouldn't have been able to become moms now do everyday.
7 years, 3 m/c, 1 failed adoption.......infertility stinks...big time
but sitting here holding my 15 day old baby girl (that resulted from IVF) makes it worth every second.
hang in there.
and since you are over 35 i'd recommend seeing a fertility specialist sooner rather than later.
