I am not a big heel wearer for daytime/ work, but I wore high heels right up to the end of my pregnancies if I was getting dressed up. A woman I worked with, who is only 5ft wore her huge heels everyday until she went on leave. You aren't alone.

We are supposed to ditch them for safety reasons, but I didn't find my balance to be greatly affected. You will probably find your feet get a big bigger and your legs get tired and achey so heels will get less comfortable to wear for long periods as you get further along.
