I've suffered from IBS since I was about 4 years old so I know the pain you're going through. Mine got a lot worse in my late teens when I started drinking alcohol and not eating as well (a lot more junk and less substantial and frequent meals - typical 18-20 year old). I did finally learn what my triggers were and that a healthy diet (with LOTS of vegies!) and regular exercise really helped.

When I fell pregnant, my IBS kicked in straight away as I suffered terrible morning sickness (24/7 nausea) and just wasn't eating properly. I ended up going back to a daily dose (or two some days) of Metamucil and it helped so much. Once the morning sickness disappeard (around 18 weeks), I started eating regular, very healthy meals and drank a lot of water. My IBS had never been better - it was pretty much non-existent throughout the rest of my pregnancy but I did have to continue with the Metamucil every day.

What you're experiencing is very normal. A lot of your organs are affected by pregnancy and our bowels slow down considerably with all the hormones that come with pregnancy. I highly recommend a good does of Metamucil (or Benefibre) daily.

Good luck!
