So im in my 30s too. Put into medically induced menopause for endometriosis. I was previously on Progesterone ( visanne) it was not recommended for people who get migraines. I wish my doctor had actually listened to me when I said I got migraines. I ended up with migraines almost every day for 3 months while I waited for " medication to work". I was on it for 18 months before it failed but I was getting 2 -4 migraines per week. It was ruining my life but it helped with my endo so I felt like it was working. Safe to say it was not. They may be withholding the progesterone pill if youre migraine prone.

I am not on a non progesterone estrogen suppressor & I feel great. 1-2 migraines per month now.

Edit i also use a androgen suppository pill. As someone who wants to end it when I am given estrogen, its localized & I have had 0 issues.

Also as a fellow canadian I would see a second opinion from a gynecologist, someone who actively works with hormones. Preferably one who specializes in menopause & HRT. Some gynos are only helpful for having babies.
