Pms or pregnancy

I had sex on the 9th Feb, it was protected and he pulled out. I had my period on the 17th, a normal full period.

But since last week my stomach has been bloated, had cramps (not the painful kind), my emotions have been all over the places and I’ve been experiencing food cravings as well a little nausea and headaches.

Is it possible to be pregnant even though I had a period last month? I know I sound dumb but I’m really anxious right now

And my period is due Saturday but this doesn’t usually happen during my cycle
