Could you actually be constipated? I know it seems weird, but sometimes (here comes some more of that TMI!!) if you are really backed up only small amounts can come out around the edges (sorry, it's gross). So it looks for all intents and purposes that you have gastro but are actually constipated.

Either way, I would still get it checked out.

There is no law out there stating that because you are pregnant you must suffer in silence and be uncomfortable!!
