I know your teeth and gums can go crazy when you're pregnant and my gums are so sensitive/loose and bleed easily now. I tried to make a dentist appointment but they can't see me until after my due date. Is there anything temporary I can do to stop the constant bleeding? When I floss my gums feel like they are falling apart😔
