First day of progesterone shots!

Champlin • Mommy to a 3 yo prince and due 04/22/18 with a little princess ✨❤

I went into the high risk doctor today for a transvaginal cervix check and to start my mikena injections. I was so nervous because I've been told it is very painful due to it being oil based but to my surprise, I didn't feel a thing (including when needle was put in & when the injection was going in) I was wondering does it get more painful as the weeks go by?
