I took Plan B within two hours of the condom breaking. I took 3 pregnancy test and all came back negative. The only thing is I started birth control the day after the condom broke. I recently went off it because of the side affects I was having. Could I still be pregnant or am I just over reacting?

There is always a chance you could be pregnant. No form of birth control is 100% effective, and Plan B does have some incidences where it did not work as expected. Unfortunately you are now playing the waiting game and have to wait for your next period.

I have had two periods since I've taken plan b, I don't know if that was the birth control or not though.

In that case, you most likely are not pregnant.
