Could I be pregnant?

So I could be pregnant. I took a test 11 days after I had sex, but it was too early. then I took another test a week later. Both tests were negative. but I've have been having all the symptoms. vivid dreams, nausea, frequent urination, digestive problems, lack of period, breast tenderness, lower back pain, food asversions.

I literally feel pregnant. but all the tests are coming back negative.

Can someone help me on this one lol
