Weird cycle

So last month I was a week late ovulating so I was a week late for af. This cycle I'm 98% I'm ovulating. I have mild cramps but definitely noticeable and more fertile mucus than I have had in months..... I'm not due to ovulate for another 4 days. My cycle just seems to be boucung around. I knew when I ovulated late last month I had the mucus and the cramps. Anyone else have off cycles sometimes. Most months I have almost no ewcm today I seem to have buckets of it.
