Hi everyone, I posted a few months ago about a question. The question rwas, i had umprotected sex if you months ago, and I asked all of you if I was going to have a problem because of the fact that I took plan b I was so worried that I wasn't going to get my period.  I did, a few days late I did. Now, two months have passed and I'm having a problem.  I haven't had sex thus time, but now I was supposed to getmy peruod October 21, and now it's two days later, and I haven't gotten to yet. Why is that? I need some help from all of you.
