Luteal phase shouldn't vary, right?!

Ugh, I need some people to tell me off for being silly please, while I have a bit of a rant!

I'm only on my third cycle since Mirena coil. But for my first 2 cycles, my LP was bang on 14 days (I am temping so pretty sure I have it spot on). Cycle 2 I ovulated CD 14 (confirmed with temps and I get ovulation cramps too) then LP was 14 days exactly.

I got a +ve OPK slightly early this month (so dutifully DTD) and then I got my temp shift and ovulation cramps clearly on CD12. Bit weird that it was early, but all the signs point to it being CD12. My temps have been a bit low and unclear this cycle but in my opinion my ovulation is mega clear on my chart (attached it in case I'm wrong).

So I was due AF yesterday on 15 dpo. I'd been getting BFNs since 11dpo, I don't feel any symptoms and I don't feel pregnant. Thought it was a bit weird to not get AF yesterday, and was so sure I'd start today that didn't bother testing this morning. But now it's after lunch on 16dpo and still no sign of her! I thought I had some cramps earlier, but I think that's my tight work trousers on my Christmas bellly!

So I am literally only ONE day late but of course it's messing with my head. When they say LP doesn't vary, I'm guessing they mean it doesn't vary MUCH, and that one day isn't crazy? I really don't think I'm pregnant (I would have got BFP by 15dpo surely, and I don't feel pg, and my temps are pretty much down to the coverline) so why on earth is that horrible witch trolling me like this?

Thank you for letting me rant!

I would say it’s possibly an anovulatory month. There is no clear temp shift. An opk can be positive and your body not actually ovulated. Keep doing opks. You may ovulate later.

I guess it's certainly possible. It could explain why I had very little (next to no) EWCM this cycle and my lack of AF symptoms. My temps are a bit whacky but I've found in the past that my pre-O temps can be pretty up and down then more stable post-O.

But then FF's estimation lines up exactly with my day of crampy O pains that I tend to get - it definitely FELT like I ovulated but you've certainly got me questioning it now.
