Personally, I think if it's not too high at all then I'd go for it, like on special occasions and events and not on a daily basis.
I remember Victoria Beckham wearing her 7 or 9 (not sure) inch Louboutins. I still consider myself a kid back then but when I saw that photo of her wearing that high of a heel with her huge bump, I couldn't avoid to just not my head in shock.
