You can try to conceive for second time, but, you'll need to wait at least a year.
If you conceive earlier, your chances for placenta abruption are much higher.
There is a clinical data about an increased risk of placenta abruption when conceiving a second pregnancy within a year of a cesarean.
Women that have experience this pregnancy complication have 15% risk to experiences it once more in later pregnancies.
Pregnant women after forties and women with excess amniotic fluid also have greater chances for placenta abruption.
This complication can't be predicted, but, the pregnant woman will need to have controlled blood pressure, blood sugar levels and to avoid smoking cigarettes.
Best wishes!
