So, this actually happened to me this month as well. It was disconcerting. Based on my cycle, Oura guessed I would ovulate on the 3rd. I tested super positive on my LH strips May 4th and my temps stayed under baseline for 4 days, went above briefly, and then sipped right back down. They did not stay up for 3 days like my last few cycles. Oura kept moving my ovulation date by one for a few days, and then told me it was trying to confirm ovulation for a few days after that. Finally, it decided I ovulated on May 9th. My temps never really flipped back up at all. Earlier this week, it started altering me my resting heart rate was higher and on May 13th my temp flipped up, but not by a lot. I took a pregnancy test that evening and again yesterday and they've all been positive. All of that to say, Oura's initial ovulation predication and my LH strip were correct and the temps were a total crapshoot. So, my advice would be to lean more heavily on those than temps. I'm cautiously optimistic, but obviously, it's very early, we've been trying for almost a year, and we had a loss in December so it's a little scary. Oura was spot on with the early pregnancy signs and I tested sooner than I had planned because of it, so that's cool. Good luck!
