I was wondering if i could be pregnant because my "boyfriend" pulled out a second before he ejaculated. . (he was not wearing a condom)?

20-30% chance pregna: No using any contraception (even if coitus interruptus is employed) may have up to a 20-30% chance of pregnancy per cycle - depending on your age. Take Folic Acid 1-5 mg daily and check a urine pregnancy test within a day to a week of a late/missed period to find out! if pregnancy is not desired and you are still within 2-3 days of the sexual encounter, consider Plan B morning after pill.
