could I still be pregnant?

Hi everyone! So I was wondering if anyone has had a positive pregnancy test 10days after missing there period when already taking one 5 days after said missed period that was negative? I was supposed to get my period on 6/28 haven't gotten it yet, took a test on 7/2 that was negative. I've had irregular periods in the past but the last 6 months I've been consistent, between 24 to 37 day cycles, which is good for me, I used to have 50+ day cycles. Any comments of hope would be appreciated! 😁
