Hello. Thank you for your message.

Foreplay does not cause pregnancy. There is a risk of pregnancy when a woman has unprotected sex with ejaculation inside the vaginal canal.
Stress is likely affecting your period. For future, have your partner wear a condom during any kind of sex play so you need not worry.
