I have had a bit of a dodgy tummy since being pregnant, I wouldn't say I have constant diarroeha but every morning it's definitely a lot 'looser' (sorry TMI) like I wake up and I HAVE to go, get the while tummy ache thing. But once I've been in the morning I'm fine for the rest of the day. Are you going throughout the day? If you are getting it all day every day, like Sleepy Sue said, you should get checked out. x x
