Pregnant after plan b?

My husband and I had sex on the 22nd (day 9 of my cycle the 14th was the first day of my last period) and the condom broke and he came inside me. I took plan b the next day. Since that night (the 22nd) I have experience cramping, pelvic pain,  nausea, and today thick white discharge. Has anyone had similar experiences and ended up pregnant/not pregnant?
