I don't use the pill, I go with Depo, lol. The doctor was baffled when I nearly passed out/got sick from getting my blood drawn the other day, and that I hate needles, and yet still wanted the shot.
The reason being that I have a terrible memory and I know that I wouldn't be able to remember to take the pill every day, and last thing I need is to miss it, I'm definitely not ready for children. At least I can more easily remember an appointment every three months as opposed to taking birth control every day. That, and generally, I can handle a shot as long as it's quick. Blood drawing on the other hand, not so much.
