morning after pill, heavy period, still pregnant?

So on the 6th of February my boyfriend and I were fooling around. We only had contact with each other's genitals and then he fingered me deeply. I know he had precum on him because I felt it before. 12 hours later I took and EC Pill to settle my mind and calm me. I had a light bleeding a week later. The next month (March) my period was 8 days late but I got it and it was very heavy, and last 6-7 days. I spotted 3-4 days after it ended. Now I'm worried because I'm still bloating and having soar breasts. But my period ended the 24th of March and it's the 4th of April. There is no way my period could be coming. So is it possible I could still be pregnant?
