The question “Which one is the best?” is just not realistic. The pill affects every person differently. I’ve tried 6 or 7 different brands (I take them for PMS related symptoms), and the ones I had liked the best are the same ones that my friends hated the most.
Also, it really depends on what you’re looking for. If you just don’t want to get pregnant, then the ring is awesome. If you’re looking for lighter periods or fewer days of cramps, it’s not for you.
I’m using seasonal right now, and I think I’m going to stick with it for a while. It’s the one where you have 4 periods a year. That part is pretty nice.
You’ll need a prescription anyway, so just tell your doctor what you’re looking for, and you two can work out the best type for you.
