Ummmm....HELP

Hey guys!!!! Soooo I’m worried I might be expecting!! My situation is basically this...a guy I’ve been seeing for a while and I decided to have sex and he wore a condom and I’m on birth control. On top of that we didn’t go for long because it was really uncomfortable for me. Now Ik y’all probably think “this girl is crazy” but idk I’ve been paranoid. I have had an increase in appetite, certain smells make me nauseous, but it’s not that bad, and I’ve been feeling extra sluggish after everything. My period is supposed to start sometime this week but I’m still super paranoid. What are y’all‘s opinions????
