I'm wondering if I'm over doing it somehow.....I'm 22 weeks today, mother of two active boys and working 16 hours a week(2 days a week; 8 hour shifts; 10pm-6am) I noticed today after my third day of a long shift( I worked last Friday same hours as above) that I'm swelling and having itching/swelling in my hands and feet. I'm on my feet all my shift when I work, baby has been moving, I've been having headaches with sometimes causing spots. I don't have a appt with my ob until wed. Should I be worried about something?
