Somebody please help!!! I’m 15 and i just had my period a week ago and a day after i got off my period i had sex. which was Saturday night and now its Wednesday and i’ve been vomitting since yesterday and my tummy has been hurting and i’ve been really thirsty and i’ve been somewhat dizzy and i’ve been tired but i’m always tired…do you think i am pregnant or do you just think its all in my head??
