IBS & pregnancy

So I have IBS.. I go through spells where it’s ok and then there’s times everything bothers my stomach. I’m 11 1/2 weeks pregnant and my stomach is killing me almost daily and I spend so much time in the bathroom it seems.

Any tips on cutting certain things out in a healthy way while pregnant? This is my third child, but my IBS has never acted up this bad before and I honestly can’t take it much longer.
