How does this make sense!?

Okay so over this past weekend I took three pregnancy tests. They all came back positive but it's a faint line I was only 8 DPO yesterday I took another test at 11 DPO and still I had the same results. My doctor ordered a blood test but it came back negative?? Has this happened to anyone before!? My doctor said he would want to retest in 1-2 weeks if I have further concern.. at this point, I'm just waiting to see if I start my period. 🤷🏼‍♀️
