Am i pregnant

So i’m 16 (legal age of consent so don’t worry so is my boyfriend) and im also on birthcontrol, the last time i had sex was on valentine’s day and i was past 7 days of my birth conrol so i know i was protected. However we didn’t use a condom and he didnt ejaculate inside me. I’ve also had my withdrawal period like a few weeks ago wich lasted 4 days and i’m pretty sure longer but i ended up starting my pill again after 4 days of my period. But recently my stomachs been bloated and hard, my backs been hurting, my boobs ARENT sore so that’s a tick off of the list, i’ve been peeing more than usual and i’ve even very gassy. These things are lowkey normal for me except from the stomach being hard and bad back but i’ve also been having heart burn. Could i be pregnant? I’m going to take a test soon but i just wanted others opinions before hand so i could calm my nerves 😞
