Swelling and headache

Liz
Need some advice. At my last prenatal visit my blood pressure was elevated (132/something) and my doctor told me to let her know if I had headaches and/or blurred vision. Last night my feet, which have been swollen already, became extremely swollen and have stayed that way. I had a terrible nights sleep and have been drinking water like crazy. I know I'm not dehydrated but now have a terrible headache for the last 2 hours or so. Trying to decide if this is just normal pregnancy issues or something I should be worried about. I'm 38+1 today.
