Cramping since 3DPO

Ya

I ovulated this month on the 7th and 8th and me and DH have been doing the baby dance ever other day 4 days before I ovulated and 3 days after. Ever since 3DPO I've been cramping more to the right and occasionally a flutter feeling going cross my pelvic area. I'm 8DPO(?) now and it's more progressive almost like period cramps but no period. AF is due in a week and the other symptoms I had so far are creamy cm, tender breast and lower back pains. My joints also start to hurt. I occasionally get nauseous and headaches as well.

Could this be pregnancy symptoms? Is it possible that I'm pregnant? I had a light tint of brown discharge but only for a wipe and haven't had anything else since then and cm has dried up some.
