Hey wonderful ladies, I need some opinions please...

Scenario:
I woke about about 5am which is normal for me and I always wait until about 6.30 to take temps and it never affects them badly.
This morning I took my temp at 6am because DH's alarm went off and I stupidly thought it was mine. I had also for a split second opened my mouth before I realised it and speedily shut it again.
I have a 2 decimal place BBT therm and came out with a 36.69 temp, took it 20 mins (after lying quite still with mouth still shut) later to check consistency and it was exactly the same temp.

So my question is, does this make it a legitimate temp or have I stuffed it??

please.
