I think you O'd CD26 so that makes you 10DPO now. Some people get a +HPT that early but others don't. It depends on when implantation happens. If you implant early then you get an early result but if late you may not get a result til AF is due or late.

The high temp that FF is using to base O on looks completely out of place on your chart, but the rise on CD27 looks more like a normal thermal shift due to O.

Your pre O temps are low like mine are when I temp (if you have a look at other's charts you'll find a lot of women have higher pre O temps than what you do, not that it's an issue, but it's just harder to compare your charts to others because of this).

On the cycle I conceived my son I was sitting at 36.6 at 10DPO so similar to where you are sitting at the moment. By then though I had already had a 2 day temp dip (36.1) at 6&7 DPO. By 12DPO I was at 37.0 & that's when I tested positive - I had never had such a high temp before.

It's hard though if you haven't charted before as you have nothing to compare it to. This chart could be completely normal for you, or it might be a very significant one.

I'd be watching out for a higher temp tomorrow. If it goes up again I'd say you are in with a chance. Best of luck.
