What does my bbt chart mean?

[Praff13]

Hello,

so I’m still a bit confused over bbt charts but I’ve never had one that looks like this before, what does this mean? Any help would be very appreciated, thank you :)

For reference I am not due at for another 5 days so unsure as to the dip in temp

Just a random dip in temp - maybe you woke at a different time, it could be anything. I wouldn't read much into individual temps - it's the overall pattern that tells you what's happening.
