Confused about BBT

My husband and I and trying for our second. This is the first cycle I’ve been temping along side using OPKs as well. I’m confused about the temping part and feel like my temps are all over the place. I have been temping around the same time every morning before getting out of bed (there’s been a couple times I’ve had to temp earlier due to getting up early for work). There’s been a few times I’ve gotten out of bed to use the bathroom or whatnot and then gone back to sleep for 2 more hours before temping (don’t know if that matters). Based on my chart does it look like ovulation happened? I’ve read there’s supposed to be a temp rise after ovulation for like 3 days or something? Doesn’t a positive OPK mean ovulation will happen within 12-48 hrs or so? Just looking for advice as the temping part is all new to me. Thanks!
