Hi, I m wondering if it s possible I could be pregnant. I woke up on Monday and felt very sick and faint, and ended up vomitting (thought it was food poisoning), then last night felt off and didn t eat dinner. Now today I almost fainted this morning eating a muffin and have felt nauesous and sick ever since. I had my period last week starting the 27th July and finished on Saturday, then had sex with my boyfriend on Tuesday. Please help??
