Pregnancies now last a year and a half. Once she reaches the third trimester there is kind of hibernation for the baby. Doesn't hurt the child of the mother, she just stays large for over half a year. However endorphins and other happy chemicals go into overdrive, so all pregnant women stay in a mild bliss. They are calm, agreeable and they love it.

Feminists who don't think women should be having babies will have their biological clocks triggered by phermones, increasing until they just can't stand it anymore and need to get knocked up.

Is this a good change to reality? Probably not.
