If I bled 4 days after taking Plan B could I still be pregnant?

So I ended my period and 2 days later I had sex and the condom broke. About 2 hours later I took the Plan B pill and I think it was before i started ovulating. About 4/5 days after I started off with a brown discharge and a couple days later it got redder. Not sure if it was my period because my period wasn't due for about another 3 weeks. Now I'm kind of paranoid because I'm getting sharp pains around my ovaries and feel really bloated. I've been looking for other symptoms but maybe it's too early to tell
