Ive had this phobia for about 10 yrs and ive got 3 kids now, i felt exactly the same as you hun, i lost loads of weight in the first 12 weeks of pregnancy coz i didnt want to eat incase i v*. But with all 3 i only ever felt n*. I never v* once or in labour. Its so worth it in the end though :-) and theres so many things nowadays that can help with the nausea anyway....i say go for it xx
