Starting again

We tried #5 IUI in May, my period was 3.5 weeks late. Decided to take a break. Got my period friday. I'm gonna start prepping my body for another round. Most likely going to try next cycle. I'm really nervous about it. I want this baby so bad but I don't know if I'm ready for the heartbreak again. When I go to see my doctor, I'm gonna talk to him about a possible IVF consultation and that really scares me. Any motivation would be so helpful
