Crohns and pregnancy

Hi!! I have Crohn’s disease and I’m 8 weeks pregnant I have severe stomach pain same as when I really need the toilet kind of?

Is this normal for a crohns pregnancy

Also how did crohns affect your pregnancy differently x

Would love to know x

Also could you deliver naturally? As my midwifes are saying I’ll more than likely need a c section but I don’t understand why x
