Charting Newbie - please help!

Ka

I started charting toward the end of my cycle last month & have been consistent this month (minus one day). This is also the first month I've tried using OPKs. Should I have start ed using the OPKs sooner? Have I ovulated yet? Glow originally said my peak day was 15th but keeps pushing it forward because of the negative ovulation tests so now it shows today as the peak day. (Please forgive the lack of BD. It's been a crazy month & we've been sick.)
