Temping help!

Cassandra • Married the love of my life 13 years ago on October 23rd! We have three perfect Chihuahua furchildren, Lizzi,Rebel, & Kylo!!!
Okay, I just started temping & everything has been fine but today I got a dip. I honestly don't understand lol. I have pcos & have never ovulated on my own, so I'm not sure if this is good or not. I've added my ff chart. Thanks!
