Updated chart, still new to BBT- please help meeee!

Ki
Ok I've posted this months chart a few times in this group at this point- it's my first month trying to record BBT and it confuses me. 
​My average cycle is 31 days, I'm at 32 days & 12 days past ovulation (according to the app) and my temperature is warmer today than my usual average. 
​Anyone able to translate this for me? 
​Also, I could have sworn I had sex after the 15th- but I hear sperm can last up to 3 days, so is it possible I could be pregnant or am I just being a dumbie and aunt flow is just messing with me?
