When is enough, enough?

This past Wednesday, I met with a fertility specialist from Salt Lake City. It was a small answer to prayers. I knew my next step was to see a specialist but I knew it was going to cost money we really didn't have. The cost to travel to Salt Lake, the hotel, and the insurance copay, if they covered it. I got a call a couple weeks ago from my OBGYN's office saying that they had a specialist coming up to Rexburg and was offering free consulations. What a tender mercy. I didn't want to get my hopes up, but I really want answers. Answers to what is causing my miscarriages, why am I loosing them in the second trimester, and is there anything else I can do to improve my chances of carrying a pregnancy to full term? Many of you don't know that I lost another pregnancy in October of last year at 16 weeks, which made my 4th miscarriage in 3 years. I just want to know that I've done everything I could to bring another spirit into this world. I've pretty much dumbfounded the OBGYN doctors here, so they recommended me to a specialist. I didn't really know how much he could help me. My problem isn't getting pregnant it's keeping the pregnancy. He went over all the tests that he would recommend. Thrombophilia Panel (Already done- came back normal), Thyroid (Already done- came back normal), Diabetes (Already done-came back normal), Hysterosalpingography (Already done - came back normal) He said I've already been tested for most of the tests that we would recommend. That made me feel good that the doctors up here have been on top of things. The specialist did recommend a couple of other tests but I just don't know if they will bring me any closer to finding the cause. I just don't know. Well, at least you know what keeps me up at night. I know that I need to trust in Heavenly Father's plan and if we are meant to have more children, it will happen. If we are done having more children, than I am incredibly blessed for the children I have to fill my home with love and laughter. Overall, I'm glad I was able to talk the fertility specialist. He gave us a few options to think about. Are we any closer to finding answers, probably not. I'm I closer to making a decision...maybe.
