my boyfriend and I had a accident the day after my period ended, the condom broke, and he feels that he did not pull out successfully all the way, he found stuff on the sheets, but he was afraid so i went and got plan b and took it 14 hours after the incident, a week later i bled for three days which is two days less then my normal period, it also came two weeks early and now when i am usually supposed to have my period it has not come yet, i took a hpt and it cam out negative, is this the result of taking plan b? also I thought I ovulated a week ago, there was a clear gel substance on the toliet paper, but still no period, please help.
