Starting first round of IVF. HCG injections

Caitlin
My husband and I have miscarried 3 babies, and then had one chemical pregnancy. 
We have been infertile for about a year. I am starting my treatment now. 
CD 1. 
Have blood work on CD 3 and then ultrasound with HCG injection on cycle day 13. 
Anyone that has had these and can give me any advice or success stories I would really appreciate it.
