What Causes Bloating Along With Abdominal Pain Post Intake Of Plan B?

It has been 10 days after I took plan b, the guy was not wearing a condom and finished inside me, took plan b one step the next morning probably 10 hours later, I have been bloated and have been having stomach pains the following 9 days after, I'm afraid I might be pregnant . Are these symptoms of plan b? Or pregnancy?
