"me and my boyfriend had sex for the first time. we used the withdrawal method which is a very stupid thing to do. he was positive he didn&#039;t cum in me but i was still scared. i took plan b 16 hours later after the incident. i experienced tender breasts for about two days and light cramps also. then i spotted for 2 days extremely light, i for sure thought it was implantation bleeding. we stressed for a week straight. we&#039;re way too young to have a child. i started to experience pregnancy symptoms like breast tenderness again and frequent urination. i was so scared. then in exactly one week of taking the pill the cramps came. the second day was worse and the period came! very heavy and clots. don&#039;t stress yourself. the pill works!"
