PIO and redness/itching

Brittany • Mother of 2 boys( 6/11/08 and 7/4/17) DH had vasectomy, IVF fresh cycle #1 BFP November 2016, Baby born Independence Day 2017, can't wait for baby #3 in a few years! 👶🏽💙❤️💙❤️
I've been on PIO for almost 3 weeks now and my rear end where my injections sites are so irritated and itchy. Any recommendations to make the irritation go away? I'm a little nervous to take any anti itching steroid creams because I am 6 week.
