Did you let yourself get excited/hopeful on Clomid?

We've been TTC for over 2 years and there's no clear explanation as to why it hasn't happened. My dr started me on Clomid, but I'm trying to not get my hopes up too high. I'm afraid that if I go into this wholeheartedly thinking I'm going to finally get pregnant and it doesn't happen, I will be absolutely crushed. If this doesn't work, we aren't going to move forward with IUI until we have the money saved up for it - which only adds to the stress. I'm trying my best to relax and maintain an "if it happens, it happens" mentality. (I'm already struggling!)
