Pregnancy?

I was on the pill for four years, I just recently switched to the ring the day after I took my first pill of the pack. I had protected sex on day 9 of my cycle (three days after putting ring in and a 28-29 day cycle) I’m have the same discharge I always do with BC, but I’ve been having cramps all month and my breasts are kind of sore. My period is due tomorrow hopefully. I shouldn’t worry, right?
