Well there's always condoms and spermicide, but that's less effective of course.

There are non-estrogen types, like the mini-pill, depo, Mirena, implant, which all use progesterone and probably won't interact with whatever you're taking (but you'd have to check with your doc, of course).

Or non-hormonal types, like the copper IUD (paragard) or barrier methods.

IF you cannot use hormones, the BEST birth control for you would be PARAGARD.

It is a non hormonal IUD, and it does not interact with or interfere with any other medications.

Paragard is a good idea. I just got it because the doctor wanted me off hormones.
