Pregnancy Indication Device
The Pregnancy Indication Device is a gadget included in Creatures 3's Medical Bay. It can measure the progression of a pregnancy in a particular creature by a red glow appearing in the middle of the device, which glows bigger and brighter as progesterone increases during a pregnancy. Note that progesterone is also in the bloodstream for some time after pregnancy, and so your creature may be recovering from a pregnancy rather than expecting. In Docking Station, the Hoverdoc's Creature Care Kit is also capable of showing whether a creature is pregnant, and monitoring the buildup of progesterone in the bloodstream.
