Has levonelle still left me pregnant?

Elenor
The boyf didn't quite pull out on time, so the next morning (6th november) I took the levonelle pill. I had really bad stomach pains the evening I took the pill but that's supposed to be a side affect.. 
I had dischargey blood (idk if it was period?) for a couple of weeks about a week after I took the pill but other than that I haven't had a period since the end of October😔 
could I be pregnant??
