Temperature dip?!

What on earth is going on this month?! I had sex twice using the pull out method a week ago (and the day after

), but my chart is so weird this month! I’ve attached it along with my previous 2 months charts for comparison (which are typical months). It’s struggling with pinpointing ovulation but my temp only every goes as high as it was earlier on in my cycle when I’ve ovulated, and now it’s back to being a pre ovulation temp but my period isn’t due for another 10 days. So confused 🤦🏻‍♀️ any help would be appreciated xx
