Thanks for all the comments. Here is an update
I went and had blood work done. I inisted that they check my hormones, my thyroid, and that they check for PCOS. AND....NOTHING!
Don't get me wrong, i am happy that nothing wierd showed up, but at least that would've been an answer! Now I am back to square one. I don't know what to do. I am so depressed. I found out that my best friend is pregnant yesterday (which by the way was when my sister-in-law was having her baby shower, which my husband lied for me, so I wouldn't have to go, and now I feel like a complete jerk!). She was told she couldn't even have kids! I am very happy for her, but come on! Doctors keep telling me there is no medical reason why I shouldn't be pregnant. So what the hell? I cannot handle one more person I know getting pregnant. It's ridiculous. I want a baby so badly. Scratch that, I want MY baby, damn it!
What am I supposed to do now?
