About ready to give up.

We have been TTC for about 4 years now. To be honest I have kind of lost track of how long because it gets so discouraging and depressing to have had been TTC for over 48 times and always had to deal with the arrival of AF 48 times. I have m/c twice and they were very difficult and painful. My doctor sends me to specialists but they all say they dont know what the problem is and I should just relax. My hubby seems to feel the same way and just says to not worry about it and it will just happen on it's own. But after 4 years is that really a realistic point of view? He doesn't want to talk about it and I end up sad and very isolated feeling. It was great to find this forum and see that there are alot of other women going through the same thing. I came on this website to track AF so that I could be prepared and it was great to find that it is so much more.
Now I'm sitting here feeling the early signs of cramps and thinking about giving up and maybe adopting (also a difficult subject to get him to discuss).
Anyways, thanks for posting your stories for me to read and thanks for letting me rant, it's probably AF causing my mood. ;)
