Could I be pregnant??

Amanda
Hi ladies! So I am about 6DPO and have been having on and off nausea the last 2-3 days. I had a sharp pinching like pain on Wednesday, Nov 11th, that went away. Now i am feeling pressure in my lower pelvic area and still have the nausea on and off. Any thoughts? Could I possibly be pregnant again??? Hoping and praying!! Due for AF on Nov 20. Thoughts and advice welcome!
