Does it sound like I’m Pregnant to you?

I am expecting my period in about three or four days but I think I am having signs of pregnancy. Is is possible to have signs this early? I had unprotected sex almost everyday since mu period and I have a feeling of fullness in my abdomen as well as it has gotten harder to the touch. I feel nauseous although I have not vomited yet. I am also very tired. Does it sound like I am pregnant to you? I know I have not yet missed a period yet i am extremly regular and I usually feel very crampy and my legs usually ache by this point before my period. Yet I have none of that now. Also I have a discharge that I don’t usually have either. i am afraid I am reaching for something that isn’t there. Am I?
