The only thing I can advise is taking a pregnancy test and finding out that way.
A good resource on birth control is Bedsider.

Scarleteen is also a good resource for comprehensive sex education for teenagers, covering many different issues relating to sex and relationships.

I also found an article about dry humping with clothes on here:
https://flo.health/menstrual-cycle/s...20the%20vagina.
Basically Flo Health says dry humping cannot result in pregnancy because it does not allow semen into or around the vagina.
