Me and my bf were dry-humping.. and he had 3 layers of clothes( Undies+ Shorts+Trousers) and I only had my panties. Could I be pregnant

Hi Anon!

Thanks for your post! Did you have sex ed at school? If not, it's a good idea to study on your own so you know how sex and the human body works. You can read books on this or search our own site. This will eliminate a lot of stress than the unknown can cause.
A woman cannot get pregnant unless she has unprotected sex (naked) with ejaculation. She would also have to be ovulating. Sperm will not travel through a layer of clothing to impregnate.

So a pregnancy cannot occur from what you did.

Best,
Susan
