am i pregnant? help!

soo awhile ago me and my bf had sex. we used a condom, he didn’t cum inside of me, and i’m on birth control. but the birth control pill i have is only recommended and given to me to help with cramps. i don’t know if that’s different then using pills that prevent you from getting pregnant. but it’s been a week and a couple days and i feel sick and nauseous a lot. i feel like i’m going to throw up at anytime. my stomach also feels bloated. is there a way i’m pregnant? please help asap. thank youu
