Swollen feet and ankles

I am 27 weeks pregnant and my feet have become so swollen that I have to wear shoes 2 sizes bigger and the straps still cut into me. I cannot wear closed shoes AT ALL. My ankles are sore from the skin being so tight and when I press the skin it leaves an indentation. Is anyone else's feet so bad and what can help? My husband wants me to go ask my Dr tomorrow if this is something to be concerned about (I work in the hospital, in admin) but I don't wanna complain about something if it's really nothing.

I put my feet up as often as I can and soak them in ice water when I'm home. Any other ideas or advice?

Oh and I am already on medication for my blood pressure, which was a pre-existing condition.
