Okay, so I feel like a right plum asking this!!

About 10 days ago (when I was 22 weeks pregnant) I started getting these waves of "oh-my-gosh-I-need-to-run-the-the-toilet" - you know the awful gripey pains in your tummy - but by the time I got there the urge had passed. I didn't think much of it, though, because I was in Egypt and fully expected some tummy trouble.....

.... but it hasn't stopped! It happens maybe a couple of times a day. I've stopped running to the toilet now, I just ride it out and about 30 seconds later it goes away!

Could this be the BH I've heard so much about??? Or has Egypt ruined me for good?!!!
