When I went to the doctor today she told me that my blood pressure was a little elevated so try to keep a close eye on it and to watch for faintness or dizziness or headaches, she told me if I experienced any of this I should go into labor and delivery to get checked.::. previously I didn't have any of this but I just took a hot shower and now my feet and hands are really swollen; could this be because of my blood pressure and should I go into labor and delivery or no??
