Question:
Mikvah after birth is it 14 days and then another 7 days after a girl or 14 days total?
Answer:
It is after the fourteen days in total for a girl and seven days for a boy. However in practical living I would not advise you to do this so close after birth, as the area can be very sore, and even making bedikas at that point can cause her to bleed.
Best wishes
