Period irregularity while breastfeeding?

I am over a year PP with my 2nd and I'm still breastfeeding occasionally. I didn't start my period back up again till the 1 year mark, which I've learned is normal. This last period I should've had would've been the 3rd one but I'm 10 days late..maybe it's just irregular right now🤷🏼‍♀️

Any other momma's experience this with their periods and breastfeeding? I have mixed feelings about this cause part of me thinks it's just irregular but part of me thinks I might be pregnant again😅
