Mine have been swelling really bad too.same situation 40+ hours on my feet a week. I've called my dr office a few times and they weren't concerned they had even seen them a couple times but def. call since at my last appointment they were so swollen all the way up my calves and all and I had protein in my urine last appointment now I'm being monitored for preeclampsia. Better safe than sorry

Call just to rule out preeclampsia or gestational diabetes

You should call. This happened to me once and I was found to have preeclampsia. You may be fine but it never hurts to make sure.
