36.9 is still well within normal range. In fact 36-39 is still considered normal unless your temp is usually below 36, I would just wait a little while long before taking a test with first morning urine. Good luck with everything.
Do you normally track your temps? Is this high and for you and has it continued to be high? How long is you cycle normally? Best to wait and see if your period comes, if not then take a test with first morning urine. You can test early, but it's most accurate to wait till the day or after your period is due. Good Luck
