Possibly pregnant? Anyone experience this?

So I still have no AF now two days late. Went to try and check my cervix which is kinda new to me anyways it was way far back!!! Also though my vaginal walls feel so tight. Has anyone experienced this???? Seems really odd!! Three days ago I took a test and got a kinda sorta faint line. I'm waiting for more to arrive in the mail!!! Really hoping this is my month!!!
