Lower BBTs?

Justine • Pregnant with baby #2 with a 6 month old... Here we go!
I just started temping this month. I think my temperatures are fairly low. A few of them I can't see on the graph like 96.6 and 96.4. Does anyone else have this problem? Is there any settings you know of that I can change to be able to see the full graph? Not a huge deal... Just a little annoying ? Thanks!
