Pregnancy symptoms usually don't start showing up until 8 weeks because until then, the baby isn't even a fetus yet. It also takes a few days after you have sex for sperm to fertilize the egg. The first sign of pregnancy is usually a missed period. I highly doubt you'd be feeling extra hungry or even nauseous because of pregnancy this early. If you're taking birth control your chances of being pregnant are slim, and technically you didn't have unprotected intercourse. However it would still be a good idea to keep trying out different condoms until you find one that works for you.
