If a woman has a positive Rh factor, there can be no Rh conflict with the fetus. In the case of a negative Rh factor, mothers recognize the Rh factor of the father. If it is also negative, there will be no Rh conflict, if it is positive, you need to monitor the blood for the level of antibodies, as they answered earlier.
My situation is the opposite. My Rh is negative in all four children it is positive. There is nothing unusual about the course of pregnancy. You just need to regularly donate blood for antibodies. And after giving birth to a child, do an expensive injection of anti-Rh immunoglobulin against Rh-conflict. But this is if you want another child.
