Faint positive test at home and negative blood test!

NeverMind🥀
I got 3 faint positive tests with FRER yesterday and today I went to a clinic to get a blood test done. The blood test was qualitative and it was negative. Have u ever experienced this before? Did u end up pregnant? My next cycle should start 2/22-2/24. I am having a lot of pregnancy symptoms.
Thank you!!!
