Taking BBT too early?

Question

I've been taking my bbt when I first wake every day at 6:50. It has been ranging from 96.75-97.1 (a few high outliers on days when I was tossing and turning all night so I discarded those).  Last week I had one day that I had to wake up at 5:50 so I took my temp and it was very low at 96.17.  My cycles are irregular so I'm wondering if that was my O dip or if it's possible the different temp time caused this. Since then my temps have been just slightly higher than usual at 97.15-97.25.  Thoughts?

Answer

I wake up at 4:45 to go to work and so on my days off, I wake up at that time to take my temperature as well. I find that if I take it when I wake up on my days off (around 7), the temperature is higher than it likely should be because I've been moving around more as I begin to wake up.

The other thing is: be sure you are using a basal thermometer and not just a regular one. I don't know why, but my temp is always higher when I'm using a regular thermometer compared to when I'm using my basal one. Plus, my basal thermometer goes to 2 decimal places so it's more accurate.

Answer

I'm in the same boat with you last month the lowest my temp would go is 96.9 and the highest 97.8 but it usually stay at 97.4 or 97.1 lately is been really low from 96.8-96.6...today was 96.6 and I've been taking it at 630 every day its so confusing I'm still getting used to charting last month was my first time

Answer

One more thing if it helps... I got a very close/possibly positive OPK two days after my low temp.
