Post ER tips?

Hi all! This is my first ER. I have PCOS and we are at year 2 of infertility. 3 failed rounds of IUI and two miscarriages under my belt. I’m on day 6 of stims. As we’re getting closer to the ER, I’m realizing I have no clue how to prepare.

How many days would you take off from work afterwards??

And tips/tricks of things you did/ bought to make it more comfortable post-procedure?
