HRT and MG

Hello! I am in my mid 40's, and my MG has always been exacerbated 3 days before my cycle starts, I've never had to track it since the weakness was always so much more profound suddenly those 3 days preceding, and the first 3 days of my cycle. I saw a new doc, who suggested I try an estradiol patch and progestin pill to take daily, to see if we can just skip my period and keep my symptoms more stable, however so far I feel so much weaker! I'm only 7 days into this experiment, trying to be patient, but it's making me nervous. Anyone else have any experience with this? THANK YOU!
