Did I ovulate?

I had a positive opk on CD 19 but no other symptoms of ovulation, I was dehydrated at the time so I’m wondering if it was a false positive. Glow marked my ovulation and gave me a coverline. As my cycle went on I believe I may have actually ovulated on CD 31 as I had EWCM, +opk, pain in my ovary, and so far rising temps. I expected glow to reset my ovulation and coverline but so far it hasn’t, I even took out my +opk from CD 19 and it made no difference Do you think I ovulated this cycle? If so, when, and how can I get glow to change my ovulation date and give me a coverline?
