Hi,

Just wondering any anyone else has ever had 2 dips below their coverline?

I didn't sleep under the quilt las night as when we went up to bed, one of the cats had kindly thrown-up all over the covers, so was in a sleeping bag, so this may have something to do with it. I know I need to see what my temps do tomorrow, but just can't find 2 dips anywhere else.

Any suggestions?

Only a week to go now before either af arrives or I can test

Thank you
