Half way through 2 week wait

The 2 week wait is the worst. It's the 14 days I have to wait to test to see if I'm pregnant. The first few days was easy. Then, I started to get anxious, reading into every cramp, twinge, mood swing, etc. A few days ago, I spent the evening with very close friends. There were 3 infants from 1 month to 8 months old. I was holding one of them while talking to my friend and I briefly started to cry. I guess it's all the hormones running through my body. I got over it quickly and just enjoyed holding all these kids. Then, I just saw that TLC show, "I didn't know I was pregnant" and a 57 year old lady had a healthy daughter. I can tell you some of the emotions I have are angry, sad, confused and frustrated. One of my friends has a beautiful little girl who got pregnant on the IUD. I just feel like she is a little miracle and I don't understand why I can't be blessed with my own little miracle.
I have been having cramps that are just like aunt flow is about to visit. I am also breaking out and being a little witch to my poor hubby. I don't think this round worked. I am staying positive, but based off my latest symptoms, I think this IUI failed. I am supposed to test on Friday. We'll see what happens:)
