Virgin's doubt

I was making out with a boy two weeks ago... And he was trying to penetrate me but... It was hurting me so we stopped... I didn't bleed nor felt like it was inside me, and he didn't cum.. He was 'there' like literally a minute or two trying without a condom ... I wasn't wet at all and I checked and my himen and it is there, But I'm 4 days late... And friends have told me is the stress that's making me late... But, could I be pregnant? I'm 19, I'm scared and definitely don't want a baby....
