Nervous

Well tomorrow will end my TWW and I am so nervous. It was our first IUI and I'm so scared to test. I want more than anything for it to be positive. After 18 months, a laparascopy and 5 failed cycles of clomid; I would be so thankful if my test is pregnant. But I know it's reality and I know it's my chances. My IUI just went so well and the follicles and sperm count were more than we could ever hope. It was so hard not to think we were finally going to be pregnant. Now I'm just at a loss. I have cramped all day like AF is going to show and I don't even want to test now. :( I just don't know how much more I can take. Dealing with unexplained infertility at such a young age really sucks!!!!!!!
