I'm 15, had unprotected sex and my period is a month late

I'm 15 and I am 1 month late for my period.

I had unprotected sex with a gym mate. As soon as we were done he told me he has a girlfriend and I am just a friend with benefits and sex partner.

I'm scared to tell my parent about this as we don't have a strong relationship.

Any advice on how to deal with the humiliation? And if I'm pregnant what do I do?
