How are you supposed to know if a scardox alien is pregnant

It will ask you, "Why is there a huge lump in my stomach?" duh.... oh and it will call you mr. easy
It is really hard to know if your alien is pregnant. The alien may not appear to be pregnant like a human does, so you may just have to wait and see if a baby is born. On the TV show, Third Rock From the Sun, when the human got pregnant by the alien, she gave birth within 12 hours.
