BBT Spike with "High" OPK

My bbt has been pretty consistent at 97.5 and today it spiked to 98.11! My OPKs have been registering "high" with the clear blue advanced. Does this even matter at this point? We have been DTD daily as to not miss the window incase the opk just aren't reading the peak but i don't know!

We are TTC our 2nd child, our first son was born in February and passed away at 10 days old due to complications from CHD. We have been praying so hard for baby #2

Baby dust to you all! 👶🏻✨
