Due date confusion?

Currently pregnant with my 3rd that was totally unplanned! After my 2nd, my periods were very short, 23-24 day cycles, but regular so when I missed my period in February I knew I was pregnant & it was confirmed! They have my EDD as 10/28 based on a regular 28 day cycle. With a 23-24 day cycle, my EDD would be 10/22. But, I think I might be further along than that because in January my period was irregular, but on time. My “period” was 4 days & very light which wasn’t the norm. I even said “my period is off” but didn’t think anything about it cause I still had it that month. Has anyone had this happen & actually be further along than you thought? Here’s a picture of my test just because I can’t believe it!
