As you said on the back. On the alien's back, if it is pregnant, there should be a long hole from the start of its head to about half of its back. Eventually it should peel off and leave a big, long hole. When it does that it means that it is ready to give birth.
if your aliens is pregnant there will be a black dot on it's head.
Stick there backs together!

Not that I know of. All the pregnant ones I have had have been female. I highly doubt that a male one can.
