Could I still be pregnant?

Alyssa

I took plan B the morning of the 15th. My bf finished inside me on the 14th, 15th, and 16th. I know the chances are very slim. But could I still be pregnant?

I took a test today and it came back negative. I know taking plan B typically means you don't want a baby, but I'm starting to wish I hadn't taken it, and hoping against all hope that maybe I am pregnant.

I guess I ought to wait til I miss my period to test again? TIA
