Pregnancy symptoms or PMS?

So I stopped my BC last month on the 13th. I took it for almost 2 years. Today I'm 10 DPO. Starting on the 6th DPO I started having and still have sore boobs, major cramping, and fatigue. My nipples were so sore I could barely touch them. Today I woke up nauseous and decided to take a PT. It was negative, but could I still be pregnant? AF is supposed to be here Monday. Should I wait until next week to test again, or to see if AF comes?
