For the question about how to get birth control, I don't know what it's like in other countries but I know in the uk the only over the counter birth controls you can get are condoms and the morning after pill. Even if you can get other stuff over the counter I'd suggest going to discuss about this with your doctor about what contraception is best for you. That way you may end up finding out the one you thought would be best for you isn't and there's an alternative that will be better.
Thanks for all the answers, everyone! I was curious, since I baselessly encouraged a friend of mine to use birth control with condoms...
