Late ovulation??

According to Glow I was ovulating on 10/6 (cycle day 15). That made sense because I got a positive (I think) opk that day and ovulated on cycle day 13 last month. However, my temp spiked +0.84 this morning and I got what looked like another positive opk. Plus, now this evening I am having intense lower left pelvic cramping. I'm on cycle day 20. What do y'all think? Pics posted below. TIA. :-)
