Cycles suddenly becoming shorter

[imjustken]

I'm 32 and have always had a 30 day cycle, since having my second child 18 months ago my periods have been very heavy, long (used to be 3/4 days and have doubled in length) and ovulation has been very painful every month. My cycle has also all of a sudden changed from 30 to 26 days, is this normal as you get older? I don't know whether to be concerned or not.

It's been my experience too that from 30 onwards my cycles slowly started getting closer together. It was 24 days at some point but very slowly, over 10-15 years
