I dont know what’s going on

I switched my birth control this month to a new one (last one was making me depressed). My estimated ovulation (according to glow) was on July 8th. I had unprotected sex on that day and the week before. My period is due in 2 days. I have this cramps that won’t go away (not super sharp) just dull pains. No bleeding. My nipples burn so bad and are so sensitive. Just wondering if these are pms symptoms, symptoms from the new birth control or pregnancy symptoms. Or all of the above.
