Did the COVID vaccine affect your period?

I got my 1st Covid vaccine dose 2 days before my cycle was due. I’m now 9 days late, negative pregnancy test. My cycle is always regular. I have searched for info on whether it can affect a woman’s cycle, but was unable to find anything. I did see info on women who had contracted Covid suffering from irregular cycles and various other symptoms related to their period after they got the virus but nothing related to the vaccine. Scientifically the vaccine should have no effect on this but I think it’s weird, my cycle is never late.

Anyone else experience this?
