Progestogen pill and taking topamirate/topamax

So I've been on Qudexy (form of topamax) for almost a year- for migraines. Anti-serizure medications are known to lower the effects of birth control but I'm not using it for the contraceptive purpose, just for cramping. My doctor said it would be fine. And I'm on the Progestogen because estrogen was making my chest hurt. I'm just wondering if anyone else takes these two together and how it's working out for them?? I'm starting next month so I'm a little nervous. I've had quite a bit of hair loss with topamax and I'm only 18
