I also had PE with DD & was told to keep an eye on it with this one aswell.
My feet r starting to get super swollen. My gp told me i had a mild case of odema. My hands only seem to swell during the night & morning. My bp is fine so i assume if it was something to worry about the gp would of said something.
I think its the heat & humidity thats doing it.
But if ur worried u should go & have ur bp done just to ease ur own mind
Hope everything is fine,i'm sure it will be
