hi, me and my boyfriend had been grinding i guess you could say but we were both naked, but he did not enter me nor did he ejaculate. I am still worried that some pre-ejaculation may have rubbed off on me and no im am worried sick. I am on the pill. I missed two pills last month but none this pack so far. I was wondering if i should take the plan b pill to be safe or am i being paranoid, im scared if i wait till my pack if over to get my period then it'll be to late to take any more caution.
