Dip in BBT 5-7 DPO

[Geetika]

Hi,

We have been TTC for the last 8 months and this is our 9th cycle.

I have been charting my BBT for the last 4 months. This month my temps have dipped from 36.5 to 36.1. My coverline is 36.

Is this normal. Could this mean that I am pregnant?

Please help...this temp drop is driving me crazy!!!
