Positive tear

I have taken 4 test and all were positive missed period last month. I had nausea last week but went away and I have been having really sore breasts. My Dr won't see me until the 17th. I am having real bad anxiety thinking that I am really not pregnant and when I go to the Dr they will not find anything. Can someone help with this. I never thought I would get pregnant because I have PCOS and me and my boyfriend have been together for 10 years and had not gotten pregnant before.
