pregnant or paranoid

I don’t remember when my last period was; it is very irregular. I am 15 about to be 16 and I lost my virginity on the 24th. I remember my period was around July 25th or somewhere around August 11th because it was when I had acrylic nails on.

I used protection but briefly he went in raw, but didn’t come inside of me.

I have a bunch of period symptoms, but no blood yet.

Is this a sign of early pregnancy or is my period just late?
