What Causes Abdominal Pain After Protected Intercourse?

So, I was a virgin until a week ago. I decided to have sex with my boyfriend, but we were protected. We used a condom. My problem is that now, 7 days later, I have faint cramping. I know it isn t my period because my period had just stopped a few days before having sex. I have noticed nothing else different and just the ominous cramping. I was wondering if this was an early sign of pregnancy? Again, we used a condom and he pulled out as he ejaculated, so I m wary as to the condom being defected and being pregnant.
