help me!!!!

so ladies i have a situation and i feel like i have no one to talk to about this. okay so i had sex with my boyfriend about 2 weeks ago then i got my period over this past week. i got off of it 3 days ago and we had sex again. but 2 days after we had sex i had light bleeding around 11am. and i didn’t think anything of it until the bleeding was light pink and it wasn’t even bleeding i was spotting. and all i can think about right now is that it’s implantation bleeding because it’s day 2 and i’m still bleeding and i’m freaking out because i told my boyfriend i could be pregnant and all he said was “that sucks.” my fertile window starts in 2 days and i’m under a lot of stress and my boyfriends an asshole. i can’t be pregnant i’m almost 16 and i haven’t taken a test yet bc i’m to nervous and i have like fuckin christian parents so i can’t talk to anyone about it please help!! am i pregnant or like wtf should i do?
