Could I be pregnant

My boyfriend and I have been trying for a few months. I had my period on the 5th of this month and it was a lot lighter than usual and did not last as long as it usually does. It was mainly spotting. I have been having symptoms of pregnancy. I have nausea, tender breasts, been tired more, and have had some cravings. I saw my doctor today and they said that I was severely dehydrated and that there is protein in my urine. That has never happened to me and I have so many people thinking that I am pregnant because of this. My doctor didn't do a pregnancy test because I told her that I had my period this month. What do you guys think?
