Have you had any resolution to this? I've recently realized the patch exposes me to 60% more estrogen, after battling endo for 15yrs. I strongly believe my dr has overlooked this, & that it's one of the reasons I now suffer from widespread chronic symptoms. He refused to switch my b.c. - stating that my ONLY options were the 3 that keep him on my payroll: get pregnant, go back on Lupron, or full hysterectomy with add-back (none of which are cures). I'm stuck on this patch until I can see a new dr. & not happy about it.
has anyone answered your question? I was recently put on the patch and i have endometriosis and my first period was horrible.
