I need help understanding my period or if it’s normal at least …

My period went from coming on once a month to … twice a month back to once a month this cycle … I haven’t had my cycle since December 3rd 2024 … my next cycle said it would’ve started on the December 31st … and then glow predictor changed my period start date to this week … and it still hasn’t came on is this normal for a irregular cycle? (Btw my period comes on two days after or two days before never this late .. & also I still have period symptoms like sore breast is there a chance I still can get my period even though I’m on cycle day 36 ?
