So anxious

I am supposed to test on Monday. I had 2 IUIs almost two weeks ago. Since last night I have been feeling anxious. This is our last try otherwise we will be looking at taking a break then going into <a href="">IVF</a> or adoption. I am not sure what to do or how to stay positive. It's hard to stay positive when nothing has worked so far. Any advice? Would it be ok to start testing today?
