guys pls help me ;(

I'm a virgin. My boyfriend has never came around me, on my vagina, on my hand, on his hand etc. EVER. Even if I touched myself after I have touched his penis, is there any way I could be pregnant? I tossed him off a bit, he ddint cum and he said he didn't pre cum. I had to touch myself afterwards to change a tampon in the toilet. My hand didn't feel wet or anything g just felt weird from feeling him a bit. Should I be worried over pregnancy?
