When I had unprotected sex I took the plan B pill four days later. The day after, which is today, I am peeing very frequently. If I hold it in then I pee on myself as well. Am I pregnant?

The Plan B is supposed to be taken within 72 hours. With that said, it would be too early, 5 days after sex, to be experiencing any symptoms at all.

You now are playing the waiting game and have to wait to see if your period comes when expected.
