Ovulation

So my ovulation testing has been pretty crazy! I’ve had some really close to positive since cd 9. But Premom hasn’t read a positive one yet. (Pictures below). I’ve been BDing every time it’s close to positive for sure! Today when I wiped. My cm has a red tent to it. Could that be from ovulation?? I started out testing once in the morning and once in the evenings but then I was told it’s better to test early evenings so I’ve been testing evenings and nights. I’m not sure if I’ve even had my positive ovulation test yet and I’m already on CD 18!

Any advice would be appreciated! Thanks in advanced!
