A lil TMI

I barely post on here but I really need help ladies. I'm turning 19 and just lost my virginity, we used protection and he didn't even nut inside bc of the pain so I gave him a blow job Instead. After that he went to the bathroom and we chilled for a bit

He wanted to know what it's like going in raw because he's a virgin too and I let him bc I thought since I was getting my period in 7 days I wouldn't be fertile. He didn't cum at all but his dick was inside me for only a few seconds bc I was dry

I'm just wondering if there's a chance I can get pregnant by this, I heard pre cum gets you pregnant and im worried that he might have precame
