I'm afraid that I'm not of much help on this issue. At the beginning of this whole thing, I could hardly stay asleep long enough in the morning, to get an accurate temp. I would have dreams about taking my temp, what it would be, etc. It's calmed down for now, but I'm sure my neurosis will pick up again once I get into the 2ww!
If it fits your situation, maybe your partner could help you out. At this point, temping is just another part of my groggy morning, so my husband has a huge role in making sure that I get it done!
