Swelling and high BP but tests normal

Has anyone experienced the same thing?

I was at my OBGYN and she noted I had high BP. My mother was with me and said I looked swollen as well. We went to the ER and I was observed for a few hours. They said all my blood work came back fine and my BP went down.

Just wondering if anyone else has had this happen. My face looks a little swollen again (not like the other day) but my BP is normal for what we've seen throughout my pregnancy.

I'm 32 weeks so I know they are concerned with Hypertension and Pre-eclampsia, so I went out and bought a BP cuff for work and home.
