Can I ask about cycle lengths - is yours consistent? To some degree? Not at all?

I know the day a woman ovulates can change, but how much can it change? Slightly, a day or two? Or can it change more?

Just curious as it seems mine are all over the place, which I find odd... AF arrived 28 days after my D&C, smack on 28 days. Then last cycle was 30 days but I feel like I ovulated on CD14, which makes the LP 16 days??? This one, who knows, but I feel like I ovulated around CD11... very early for me!

Before having babies I was always a 28-30 day cycle, pretty consistent. I guess I haven't really had any sort of regular cycles in between kids so I don't know if pregnancy has altered things... also could be the mc still stuffing things round...

ETA: I'm not using FF or temping...

Experiences please! Anyone?
