Are these symptoms normal or is there a chance I’m pregnant?

I’m 18 and I lost my virginity on the 12th of February and my period is due to start in about 3 days. I’ve been on birth control for years and he also pulled out so I know there’s a small chance of me being pregnant but I’ve been having cramps these past few days and an upset stomach. I don’t exactly know if these are possibly signs of me being pregnant or if I’m overreacting and stressing myself out for no reason. I’m sorry if this is a stupid question but I’m worried. Any advice would be helpful, thank you.

Update: I got my period guys, thank you for the comments!!
