Hi,

I just starting charting my temperatures and was looking for help interpreting my chart. I've been taking it the same time every morning before getting out of bed but there's a huge spike/drop that I don't understand. I thought it stays pretty much the same until ovulation then spikes? I have a 32 day cycle and normally ovulate day 18. I just started reading Taking Charge Of Your Fertility so still a total newbie. Thoughts?
