Charters? Interpretations please!

Morning all!
We've been TTC a while now but this is my first month temping so have no comparisons and so unsure about my chart. I got my peak OPK on the 4th which matches up with a big drop in RHR and temp.
I'm now 12DPO with a BFN on an IC today and yesterday. I have some tests arriving today which I'll use in the morning but just really curious what others think of my chart so far? Anyone with a BFP happy to share theirs?
I test within the same half an hour every morning, most mornings its dead on the exact time as I have an alarm.
Thoughts much appreciated

Hey!
Looking at your chart I would say you are only 9dpo.
Did you count CD19 as your ovulation day? In my experience it would be the day before the temp spike, so CD20.
Very possible to get a negative on an ic but still be pregnant.

I chart my temp. It’s very difficult to detect pregnancy from it - I just use it to try and pinpoint ovulation (and to make sure I know I actually did). On FF would can click ‘charts like mine’ and scroll through loads of other peoples charts. You can even search for different things like pregnancy charts if you want
