Could I Be Pregnant

Ashleigh

I had sex Aug 2nd and 4th. My fertile days were Aug 4-11. I have been experiencing nausea, cramping, backaches, a heightened sense in smell, my boobs have been sore, and I’ve been fatigued. I am also 6 dpo. I have never pms’d, but idk what’s going on now. Could I possibly be pregnant and when should I take a test?
