Swelling!!

Breanna
I'll be 33 weeks on Thursday and am a full time hairstylist and salon manager. I haven't been on my feet hardly at all (especially compared to usual) and my feet and ankles are HUGE! They look like they're going to pop. I've upped my water intake and have been trying so hard to stay off them. Is swelling this much normal or do I need to ask my doctor about it?
