Sometimes I think I could... While pregnant, then I think better not!

This is meant to be a humorous thread. If you've seen the movie Pitch Perfect, you may remember the joke "sometimes I think I could do crystal meth, but then I think hmmm better not." Not as funny me typing it as it was in the movie. Anyway I was thinking us pregnant people can think of thinks we thought we could do while pregnant, but then had to reconsider. Maybe it makes you sick now or some other funny reason.
