Good afternoon, could you advise? I'm Rh-negative, this is my first pregnancy, and my husband's Rh is still unknown (we're waiting for the tests). What are the risks of being Rh-negative, has anyone had this situation? The internet says a lot, but I'd like to hear from those who have gone through it.
