Am i pregnant? or is this just me freaking out.?

Aww it's probably just you freaking out hun. Your may be sore because they're being touched more now that you're ually active. I wouldn't worry about the 20 seconds of non-condom-covered contact. Just keep using condoms (and using them correctly) and you should be okay. If you really don't want to become pregnant, you should get the birth control pill. HOWEVER it's important to know that antibiotics can make the pill ineffective, so you always need to use a backup method when you're taking anti-b's. Good luck, you can take a pregnancy test in 2-3 weeks if your period does not arrive. Til then, try not to stress
