So I've been temping for a few months now. I'm 3dpo and my temperature is high first thing in the morning (36.72) which is normal for me at 3dpo. However, I took my temperature an hour later while still in bed (just for fun) but after going to the toilet and chatting to DH in bed and it had dropped to 36.32! Surely it should be even higher than my first temperature of the day? I did it a few times to check (on both occasions) and it was similar each time! Is this normal?
