Paranoid

I’m 15 I had sex for the first time last week Friday and I’m extremely paranoid because my period is 3 days late... but the thing is I put in a nuvaring but then I took it out because of the side effects so I don’t know if it’s that or if I’m pregnant.. my worse fear is becoming a mother I might just kill myself if I am pregnant someone please help is there anyway I could give myself an abortion? When we had sex a condom was used but he did put it in raw a couple of times
