My post O temperatures are usually between 36.4 and 36.8. You can't tell anything from a single temperature though. Generally your temperatures stay high until you are due to get AF, then if you are not pregnant your temperature drops and you get AF. If you are pregnant your temperature stays high. Some people say that a triphasic chart is a promising sign for pregnancy (where you have a second temperature rise) but lots of pregnancy charts aren't triphasic. Hopefully you will get your BFP, if not then the temperatures should be clearer next cycle when you have pre and post O temps. Around the time of your period your temperatures will be very up and down.
