IVF start tomorrow

Starting my shots tomorrow AM. I'm so nervous and excited at the same time. 
My RE makes <a href="https://glowing.com/glow-fertility-program">IVF</a> sound like no big deal. I am worried about the unknown... I don't know anyone that has tried <a href="https://glowing.com/glow-fertility-program">IVF</a>. I'm just so hoping it woks the first time for us. We have unexplained infertility. Boo.
