My Ava bracelet has me confused 🤷🏻‍♀️

Hello ladies! This is my second full month using the Ava bracelet. Last month, things looked great! My chart looked normal, and I could tell when I ovulated. This month, it’s crazy! I should be ovulating within the next couple of days, but my pulse rate has been dropping, not rising. I don’t understand why it would be dropping in my fertile week. Should I just assume I’m not close to ovulating? I stopped tracking my bbt after I got the bracelet because I was becoming obsessed and stressed. I’m still using ovulation strips. They’re dark, but not positive. Any insights would be appreciated! The first picture is my chart from this month and the second is last month.
