Me and my boyfriend had unprotected sex on 20th(late night) of December. We used the pullout method and we are positive that he didn't ejaculate inside me. And he peed before the intercourse to reduce you the chance of getting me pregnant by precum.
However, on 30th around 11pm I got a really bad stomachache and after I checked my underwear I found little blood on it. And I never got that pain again. My period is due 3rd of january. But still I don't have any sings of period.

I don't have any other early pregnancy symptoms and I can keep up the all night without sleeping. Specially, these days I couldn't sleep because of my work and I am stressed out and worried because of my period. Do you think i could be pregnant? I am living in a country where abortion is illegal and I am still 22years old.
