Sad , confused

Me and my partner had unprotected sex about a week ago and he cummed inside me , it was too soon to take a pregnancy test but I'm just so excited to see if they are positive about a year ago I had a miscarriage when I was 26 weeks , & I'm scared to get my hopes up . Lately I been dreaming of me being pregnant ,& my pregnancy test coming out positive . I just want to know if I'm pregnant .
