Could i be pregnant?

[tundra02]

I had sex May 17th which was exactly 4 days after I had gotten off my period. I am on no type of birth control & he pulled out but just to be safe I purchased a plan b and took it 48 hours later. A week after taking plan b, i bled lightly for 5 days straight. Thirty five days after that I started my normal period for a week. I then had protected sex on July 6th. The next day my stomach starting pulsing like there is a heart beat. It hasn’t stopped for 8 days.
My question is could I be pregnant?
Or
Did I hurt something in my body.
I have no other symptoms besides my stomach pulsing. It feel like small cramps and a heartbeat that does not go away.

The pulsating isn't a symptom of pregnancy that I am familiar with, however- if you had sex pregnancy is a possibility.  Pulling out is still a pretty high risk- plan B  isn't always effective.  It's also important to remember that plan B can cause your cycle to be pretty irregular for a while.  I'd recommend taking a test and going from there.
