Okay so...I've only had sex twice and once was about 3 weeks ago, and I've had my period since then, and the other time was two days ago. We used protection both times, so I know I shouldn't be worried, but I really am. I've experienced sore breasts and I guess it could be considered naseua. I can't tell if it's because I'm so worried or I'm pregnant. Oh and today I experienced a very small amount of brown discharge but that's just blood I think, since I bled a small amount during the sex. Anyways what do yal think?? Ps. I've never thrown up and I've only been nauseous for like an hour.
