The way your last 4 temps have collected and stabilized it looks to me like you could be gearing up to ovulate. If you have a 28 day cycle you would likely ovulate somewhere around CD#14, this is why FF has that as your predicted O day. If your cy is longer or shorter, just keep in mind that a lutal phase is usually somewhere around 14 days. So if you have a 40 day cycle, count back 14 days from when you would normally expect AF and that's when you would expect to see ovulation (give or take a couple days). If you have a 24 days cycle, the same applies, count back 14 days from when you would expect AF to arrive and ovulation should be right around that day.
At this point I would just keep the temps you took a little later. In the future, if they make your chart difficult to read I would maybe set an alarm and try to temp at the same time... But right now they look fine to me. In the future, make down every day you have AF too and the kind of flow you had (heavy, light, medium, spotting). Also, keep in mind 1st charts can be a little bit all over the place. Think of it as a dry run
Good luck this cy
