Hormone supplementation/birth control pills and changes in strength

[aim8]

I've been taking the Yaz birth control pill (combo estrogen and progesterone) for a few years now. Last week, I was put on a progestin-only pill for endometriosis instead (Visanne), as the estrogen was causing havoc. For the past few days, I've noticed that my strength has noticeably increased. Is this just a coincidence, or is it possible that the change in pill would make such a difference? Any info. would be greatly appreciated! Does anyone else have experience with taking Visanne for Endo and its impacts on muscle gains and strength?

As an aside, any aspiring or current figure and physique competitors with endometriosis or interstitial cystitis out there? I am dealing with both and am intent on competing. Between the pills, surgery and everything else, I could use some guidance! It would be great to support each other and share what we're learning. If so, send me a request and note!
