Chart interprations?

Samantha

First month charting BBT and I had a bad cold with a fever early in my cycle so I skipped charting and have also missed a few days due to having a toddler not allowing me to sleep…but anyone want to take any guesses as to what is going on with my chart? FF says I ovulated CD13 but from what I’ve read, if you have an LH plateau for a few days, you typically ovulate a day or so after your last peak test? My peak on the CD15 was much higher than it was on CD12. My temp dropped last night and FF predicted my period would start today but I’m thinking it’s due later this week. Temp shot back up today higher than any other temp? 🤔
