I’m over it 😔🙄

My period is 4 weeks late I bought 4pk of clear blue hpt (2 stick and 2 digital) i took three test last week all game up negative. A few days ago I took the last test in the pack (a digital one) and it came up “pregnant”. I was in shock and went to target to get more test to confirm. I took a few more test later that night and they all came up negative. The next morning I contacted my doctor explaining all this and she says I can come in for a test. Took a urine test at the doctors it came up negative as well. I have no symptoms at not not even my usual PMS symptoms I get before my period comes nothing. I feel normal. I have no real answer as to why I got a positive test and a whole bunch of negative. I am confused. I’m convinced I’m not pregnant but my husband still says there’s a chance. Any advice?

PS: Due to the pandemic it’s hard getting appointments to go back and forth to my doctor.
