hi guys. okay I'm just really nervous but I had sex with a condom 6 days ago, and I'm pretty sure everything went well. I've been feeling really gassy and I noticed tonight that 2 veins stick out on my right boob. I know it's way too early for symptoms but I'm just really nervous. I'm very young and cannot get pregnant. what do you all think? please no judgement
