Early pregnancy and IBS

Hoping someone can help me!

I’m six weeks today and have medically diagnosed IBS. My main symptoms have always been severe bloating and trapped gases but managed through a FODMAP diet for years.

Pregnancy has flipped it on its head though and I am reacting constantly ☹️ I’m In so much pain and not too sure what to do. Doc visit next week but can anyone offer some advice?

Thanks!
