Really?? There are posts on this thread that stop short of a categoric 'no'? I have never been pregnant[wrong sex!] but am an MD and would strongly advise the OP against something like this. Like others have said, if things started going out of control adequate help may not be available in time.If something bad happened to the baby you would never ever forgive yourself for doing this just to satisfy your ill timed craving for a bit of adventure.
The GC is going to be there for ever and its not going to do you any special favors just because you're pregnant!
