help need some help

Is there anywhere I can go to get a blood test as my doc refusing to do one update: pregnancy test I had a pregnancy test very faint line nurse said she did but now k found out I got a uti but it been more than a week when I got this. she said to wait but now I got to take antibiotic for this uti so i was wondering if the blood test could see if pregnancy test was positive with a blood test.
