Pregnancy ?

RiRI

The first day of my last cycle was July 7th. I had unprotected sex around the 14th-15th. My cycle is late by 6 days. I’m experiencing headaches, extreme fatigue, as well as a few cravings of foods. I also started experiencing cramping on today ( feels like period cramps ) I’m not sure if this could be pregnancy or Pms?

Has anyone experienced this? What was your result?
