Okay now it looks more like ovulation, but it still looks atypical to me. From the first picture it looked like some of my anovulatory charts, I did not mean to offend, I have PCOS and know that opks don’t always work for me (had very positive tests and didn’t ovulate). The reason that you haven’t got lines is because there wasn’t enough of a dip before your rise. Meaning either you haven’t ovulated or you ovulated earlier than usual (since you normally have the atypical rise at the beginning of your cycle, normally folloewrd by 4+ days of lower temperatures before the rise.)
