I have had swelling too! mostly my legs and feet already. Good thing it is still cold here so i can wear pants and socks but it is starting to itch from the stretching. I haven't had the cloudy vision though... i think you need to talk to your doctor as well!
It could also be gestational diabetes. Sounds a lot like my symptoms I had with my first baby. Most definitely call your doc and let them know what is going on.
I would definitely call your doc! To have it constantly, is not good. First thing I thought of was high blood pressure as well. You definitely need to get that checked out.
The other day I almost passed out, but it hasn't happened since. If things like dizziness, and clouded vision are happening too often, there could be something going on and hopefully your doc can give you more info.
umm could that be high blood pressure i would calla the doctor .
