Really scared

Okay, so I’m 14 and my boyfriend and I don’t have intercourse, but, he grinds on me until I cum. So, one night we were grinding, and all I had on including a bra and a T-shirt, was some Victoria’s Secret underwear, the really lacy kind. I came a lot.

I’m 2 days late on my period and I am terrified of being pregnant.

However, he didn’t cum, And every time I ask him, he insists there is no possible way I could have gotten pregnant (no precum or anything.) But, he had all of his clothes on, whilst I had a shirt and underwear. Is there any chance I’m pregnant? I’m terrified.
