cramping a week after i lost it! am i just scared? or pregna

Im sixteen & Its been more than a week since i lost my virginity, we used a condom, & it didnt hurt afterward. I started freaking out about being pregnant about 4 days ago and ever since ive been having really bad cramps & feeling bloated. i dont feel nauseous or anything... but i think it might possibly be normal, or connected to me being nervous or thinking about it too much.

im scared.
