Should I go on birth control?

Recently had a doctors appointment where she asked me if I've ever been sexually active. I said yes even though its been almost 2 years since and it was only 1 time. (I didn't want to lie) anyways she said I'll need to come in for a pap smear which I'm going for next month now. Anyways I'm sure during the pap she will ask me about birth control. I'm not sure I want it. I've heard it messes with your body but I would really like that backup for when I actually do have sex again just in case the condom fails. What's your experience with it. Pill or other forms? I'm pretty good at taking medication I have one I have to take everyday anyways so I'd just add to it. Or should I wait seen as I haven't had sex in 2 years and don't plan on it right away as I don't have a bf right now. Plus any advice for not being nervous for the pap smear would be great cause I'm a little nervous about someone being down there lol
