NSWF Do I sound pregnant?

My boyfriend were having intercourse, we used a condom. After we checked the condom, no rips, tears, nothing. I had a funny feeling something wasn’t right and I took plan B.
My period usually comes on the fourth. The month of October it came on the eleventh.
When should I expect PMS?
I am feeling a little chest soreness and about a week ago, I felt a little queazy.
