Pregnant with IBS ???

Hi
I'm wondering if any of you have IBS and have been / are pregnant? 
I'm curious how you found it and if you had more trouble with your IBS as a result of being pregnant? 
Iv had pregnancy cramps but they got so bad last night and gave me a stomach upset so I'm wondering if it's triggering the IBS or if it's totally IBS?! Any experiences to share?
