Is there a slight possibility I'm pregnant ?

HI so I had unprotected sex with a boy when I was ovulating but I saw him pull out but he came right away. And I know it's a slight possibility of getting pregnant from precum but idk I'm scared. It's been almost two weeks and i haven't felt any signs or symptoms but when I like go to the bathroom and pee it feels different like how it would on my period. And at work today I got these two like cramps in a row. And idk im scared idk what to think. I'm supposed to get my period next week and i feel like if I keep stressing i could miss my period due to that OR I could actually be pregnant. Idk what to think
