My period is late? Help?

Okay so I'm 19, I haven't had sex, i'm not on birth control and my period is 5 days late which is pretty unusual for me. I usually have very regular cycles that are 23 days on average and I'm currently going on a 29 day cycle this month. My last period ended July 18th and my current one was supposed to start on the 10th, my next one is supposed to be September 8th. I was having a dull ache my lower abdomen near my pelvis for a few days on an off but it wasn't excruciating.

Is it normal to suddenly skip a period when it's never happened since I first got it?

Make up your mind, are your periods irregular or not?

If your cycles are 23 days on average then you can't claim you have irregular cycles - and if your cycles are 23 days on average then 29 days is still within the range for being normal for you. Your period is later than you predicted, that could be for any number of reasons including things like stress and illness, if you haven't had sex and this is a one-off then there's no reason to worry...a late period, it happens, nothing to worry about at this point.
