PLEASE HELP URGENT

Cat

Me and my boyfriend had sex 4 weeks ago and it was completely protected and neither of us came. BUT....... my period is late and I’m freaking the fuck out. Because I’m 14 and I can’t have my parents find out because I would be dead. Am I freaking out to much?! Or is this legitimate?!? I don’t want to have an abortion and I’m not ready to raise a kid PLEASE HELP!!
