It is possible to pre-empt premature births – taking care of your pregnancy and certain conditions does reduce the risk of preterm births. However, the risk may never be fully averted. Sometimes the factors are beyond your control.
You can have a conversation with your doctor on the possible date and prepare accordingly. In the interim, you must also figure out the contingencies on premature birth by speaking to your doctor and others who’ve had a premature birth.
As a preventive measure, take adequate care of yourself. Eat, exercise and rest well.
