"me and my boyfriends first time. we used the pullout method, not a smart idea. he was more than positive he didn&#039;t ejactulate but i was still very scared. we are only teenagers. i took plan b 16 hours after the &quot;incident&quot;. i experienced tender breast and spotting about 3 days later. exactly a week later i got cramps the second day was much worse but the period came! very heavy, clots and cramps. a month later no period but two negative pregnancy tests. be aware it can make next period late but take a test to be sure. don&#039;t stress, the pill works. and use protection loves."
