It could be that you had a quick peak on the 1st and are ovulating today so definitely have sex asap just incase. I would also consider continuing to test because sometimes it’s possible to struggle to ovulate and have lh rise several times without actually rising enough to ovulate. If your cycles are often quite long or irregular that’s more likely to be a concern, if your cycles are regular it’s more likely you ovulate today
You could have peaked the 30th night or maybe 31/1 some peoples peaks are very short. Like mine. You usually ovulate 12-36 hours after peak. So as long as you’ve been having sex multiple times and not just once today you should be good
It looks like you most likely peaked on the evening of day 15. As long as you baby danced around then or before, you should be in for a good shot!
