4th IUI tomorrow

I was in clinic this morning and follicles in right ovary are 1.7, 1.5, 1.2. I got a call later today to take my Ovidrel shot. This is the first time I had to inject myself. My hands were shaking and I'm a nurse for God's sake. IUI tomorrow morning. I am so hopeful that this will be successful. We got pregnant last time but lost it at 4+ weeks so I'm so hoping that we can get pregnant again. Wish me luck ?
