In need of some hope

Hello guys

we did our first round of iui and I found out today I am not pregnant. I was so sure and hopeful it would work. I am so heartbroken it's hard to put into words how I feel. This means I have to wait for my period which hurts alot, then do blood work for two weeks, tests take meds which made me so exhausted and nauseous and then the dreaded two week wait again. Of course I will do it because we want a baby more then again but I feel so shattered right now. I would love some advice, hope or success stories for iui. I honestly don't get why it didn't work everything seemed good and the levels of everything were great.
