Is it time soon?

This morning Thyra's bodytemperature has dropped to 36,8 so she should be giving birth within 24 hours, according to books but when it is about us, nothing is sure ;) Thara's bodytemperature has also started dropping, this morning being 37,5. Thyra didn't eat this morning, Thara ate but not with  good apetite, she was quite choosy and only ate the "goodies" (read: the meat). Today I'm going with Thara to see her veterinarian to have her progesterone-level determined and after that we should now more about the situation.
