"lost my virginity on the 28 of november at 6:30pm and didn&#039;t use protection (stupid i know) he said he didn&#039;t cum but i was worried of pre cum. took the pill on the 29 8:30pm (about 26 hrs after sex) and i didn&#039;t have any side effects just a little tired. my last period started on nov.9 and after 11 long dreadful days my period came on dec.9. happiest day of my life. learned my lesson for sure."
