I might be pregnant

I'm only 15 and he's 16 and we've only had sex 3 times and my period is late and sense we live in a small town and some people found out we had sex there's lots of rumors going around that I'm pregnant and all this shit and I don't know if I am but if I am I don't know what I'll do my family is against abortion so that's not an option and he's going to graduate this year I still have 3 more years of school and I'm already bullied a lot the way it is HELP
