3 positive one negitive

Okay so I am a week late on shark week and I took 1 test Saturday the 23rd and it was positive I took the second test Sunday and it was positive one regular and the second digital first response. Then I went to the doctors Tuesday the 26th and the doctors test came out negative. My doctor told me to wait another 10 days before I do a blood test. So I retested this morning with another first response test and it was positive. Do you think the doctors test was wrong? I'm just nervous. My last shark week was march 24th
