PIO Tips and Tricks?

Hi All! After hundreds, if not thousands, of subcutaneous injections over the last several years, I have to do my very first PIO shot on Monday. I used the suppositories with my first IVF pregnancy so this is new territory. I usually do all of my shots by myself because I like being in control, but my nurse highly recommended that someone do them for me. Any tips or tricks or must-knows? Here’s the kicker… my first shot on Monday morning is probably going to have to be done by my MIL while we are waiting during my husband’s sperm extraction surgery 😱
