i really need help, last month my period was 9 days late, me and my boyfriend were really worried as we did have sex without a condom but he pulled out (i know you can get pregnant from pre cum but i understand that there is a really small chance and we’ve been doing it for the past year we’ve been together), however when my period came i just figured it could be stress, since i’ve got exams atm. however, my period is usually heavy for about 7/8 days, but it’s been mild for 3 days and then competent stopped, and yesterday i had a small amount of deep browny blood, and today nothing. could i be pregnant or am i just paranoid?
