Swollen ankles

My ankle and feet have been swelling every day for the past week. I have Summer's off and have just gone back to work for the school year  ever since going back this week they've swelled, are super sensitive and they hurt!! Anyone have suggestions on what to do for swelling? I've tried Epsom salt baths and they work a little bit. I have 5 more weeks until my due date... I don't think I can handle the swelling and pain that much longer!
