Transfer day

Started my first shot of progesterone in oil this morning. I gave myself a shot in my hip. I was surprised how easy it was and it didn't hurt. Transfer day is this Friday 1/27 We are transferring our only one. It's a frozen transfer. Praying it takes and I do not have to go through another round of <a href="">IVF</a>. 
Has anyone else used progesterone in oil shots? Asking for prayers please.
