So confused!

I’ve had blazing positive opks on cd 9,13,17 and now again on 24 with dips to blanks and back up to peak in between. Normally I ovulate somewhere around cd16 with really bad pinchy cramps, but this month has been all over the place and had constant cramps. I’m 42 and trying again after our daughter was born last April. I had a chemical last cycle and Ive tested for pregnancy but all been negative (could be because I actually have no idea this time when I ovulated!). I’m usually regular as clockwork so no idea what’s going on or when to expect AF 🤦🏼‍♀️. Anyone any ideas why I keep peaking with lh?
