PMSing?

So I had protected sex on December 3rd, 7th, and 19th (used condom and pulled out before ejaculation) a few days ago I started feeling nauseous and I ended up getting the flu:/ I’ve been so moody and emotional, my boobs hurt and I broke out on my face really bad. My period is due in 3 days. I’m worried if there’s a slight chance of being pregnant or if I’m fine and just PMSing. Im also extremely bloated which always happens before my period comes
