Baseline ultrasound?

Debora • Girl born 12/2008 & Boy born 10/2017 Baby girl due November 2019
Tomorrow at 8 am I have my first IVF baseline ultrasound since I started the BC in order to start my stims. Anyone out there feel my angst? Or have any comments about how there's went? I'm obviously worried because I have suffered from stage 4 endo and ovarian cysts are pretty common to my body but I am praying to be in luck.
