Me n my boyfriend had sex on 12/3 12/4 12/6 n 12/7..we didn't use condoms. On the 3rd he didn't pull out..the other days after that he did pull out...a week later(this week) I have been feelin a lil nauseated and I smoke ciggarettes and now all of a sudden they make my stomach hurt and light headed...I don't kno wat to think...I wanna take a pregnancy test but I feel its too early! Wat should I do?
