Probably the extra blood your body is trying to supply to the baby. It takes awhile for your blood to catch up. It happened to me the first and third trimesters. Try to move slower and if u get dizzy lay down.

Why did you bold dehydration? Dehydrated or not, drinking water will help your pressures. I don't know what else you want us to tell you...
My bp is low for some reason this pregnancy. My doc told me to drinik a little caffine when I feel it drop, and that works for me. He says to try to limit it to 12 oz a day though. Low BP is pretty commen in pregnancy.
