Which temp to use? Please help!

I’m 11DPO. I had to get a steroid shot yesterday (sinus) so I slept terrible. I went to sleep around 10 & woke up @ 2 AM. I took my temp then Incase I never went back to sleep. I always test around 5:30AM. I’m a teacher so it’s very routined. @ 2 AM my fever was 97.68. I got up at 2 to use the bathroom but laid bed playing on my phone. I didn’t move too terribly much (hubby was asleep). I FINALLY fell back to sleep about 4:15 and woke up @ 6. I checked my temp and it was 98.61. I started AF cramping yesterday which makes me believe the lower number but trying to be optimistic. 😫😫😫😫
