Note: If you’re not sure what your Rh factor is, you can know by your blood type. For instance, if you’re O-negative or O-positive, that “negative” or “positive” is referring to your Rh factor. Don’t know your blood type and expecting? No need to worry; your doctor will test your Rh factor as part of the routine blood work. Photos: 25. ANKAWÜ via wikimedia commons, 24.
