Bbt chart help

[Kay1578]

Hi, fertility friend has confirmed ovulation for Tuesday. This does coincide with a opk test I'm convinced was pos positive on Monday (will add pic). What's getting me is where my crosshairs are. Would you trust this chart? Thanks

That is really weird. The "post ov" temps don't look higher enough than the pre ov ones. What happens if you exclude the super low temperature? Is that confusing it? Although that LH test does look positive so based on that I'd guess the day after that...🤷‍♀️

....which obviously coincides with the crosshairs although the temps look suspect....but I don't get what else it's basing it on, as you haven't inputted the positive OPK have you??

No I didn't input it as I was questioning if it was quite positive. Said I'd see what my temps said in 3 days, which "confirmed" ovulation. Yet I'm just as confused. Although the temps are slightly higher. They aren't much higher. And there's not 3. If I drop today's temp to 36.18 (just to see what happens and how low it would allow) the crosshairs are removed. I guess all I can do is wait till Af is due and see what happens x

I should actually have discarded the CD12 temp as I fell asleep with the heating on which I don't usually have on. That would make the chart like this x
