Hunter slept ALL night for the 1st time in a long while, which means I wasn't woke up at all last night

! He fell asleep with Dh on the couch at 8 and I didn't see him again till 8am! The problem is that I didn't have my night time wake ups so when my alarm went off at 3am to temp I was so groggy I ended up falling back to sleep with the therm in my mouth and when it beeped I reached up to grab it and.... it was on my pillow next to me LOL! And being as groggy as I was I didn't think to re-take it, instead I just tossed it on my nightstand and went back to sleep. So 6am rolls around and my alarm goes off and I realize what I did so I re-take my temp (without falling back to sleep lol).
So my 3am not sure how long the therm was actually in my mouth temp was 97.25
6am temp was 97.59
Which should I use?
