can the pill mess up cycle length?

[ShireLass]

Before I went on the pill my cycle was 4 weeks long and AF would show up almost to the same hour each time. Since coming off the pill my cycle has settled down but now it's off a few days each time and can start at any time of the day or night.

I've been using Monthly Info (https://monthlyinfo.com/) to track mine as we've been using "Standard days" to avoid pregnancy since I came off the pill. (for anyone who's not heard of it: https://pregnancy.lovetoknow.com/wiki/Standard_Days_Method)

This is a screen grab of my cycles since I started tracking them:

Any idea's why it would have done that? Is it just an age thing or did the pill mess me up?

I was on the pill from 06 or 07 and stopped it in October 09.
