Is my period coming or is this pregnancy?

So i thought i have (or could be) expercing pms symptoms.

For like 2-3 days i have been cramping, bloating, back pain, acne, craving sweets, sex drive high, etc

I feel like I’m on my period but every time i check there nothing.

I feel like i know I’m not pregnant bc i only had sex 3 times and 2 times he cum in the condom and one time he cum in my mouth.

Normally, i can tell when my period comes but this time it feels like I’ve been bloating in my stomach for most of the day.
