A lame attempt at birth control which has a fairly high rate of unintended pregnancy, such as pulling out.
My new boyfriend thinks pulling out is birth control. I tried to tell him we were playing maybe baby. Guess I can start buying baby clothes.

what you feel you have inside your tummy when you're not sure if you're actually pregnant.

the feeling is especially pronounced when you're particularly anxious to have or not have a baby.
"Well, I have a maybe baby. I still have to wait a few weeks to know for sure. But I'm so excited, I can actually feel it growing!"
