I try to drink over 100oz a day but still have had the swelling since about 32 weeks... If I get up and go for a walk for a couple miles it helps, it's when I'm standing or sitting that makes it worse :(
I woke with my feet this way... I've been elevating all morning as much as I can. never had any problems with preeclampsia. I've been drinking at least 66oz of water and more if you count juice.
Most of the time is water retention with my first pregnancy I was swollen most of the pregnancy even my mouth breaks of swollen and I had my daughter exactly on my due date !!!!
No, some swelling after being on your feet can be normal at this stage. If it got really bad, wouldn't go down after resting/elevating your feet/drinking water, then you might want to let your OB know. That combined with high blood pressure could be a sign of preeclampsia. How do you feel otherwise?
