The contraceptive implant, progesterone only pills and condoms can be commenced safely at birth or soon afterwards.
Contraceptive injections are suitable for some women immediately after birth, but if you have an increased risk of blood clots you may need to start this from 6 weeks post-delivery and/or choose another method.
Hormone and copper coils can be fitted either at the time of Caesarean section or soon after vaginal birth. If they are not fitted within 48 hours of delivery the fit will need to be delayed until at least 4 weeks after birth.
Combined hormonal contraceptive methods (combined pills, patches and rings) are not safe to use immediately after birth due to an increased risk of blood clots post-delivery. For some women they can be started 3 weeks after birth, but if you are breast feeding or have increased risk of clotting you may need to wait until 6 weeks or you may not be eligible for these methods. Your healthcare provider will be able to advise on what is suitable.
Diaphragms are not recommended in the first 6 weeks after birth due to the changes in shape of the neck of the womb and vagina which mean they may not be as effective at preventing pregnancy.
Fertility awareness methods are less reliable after giving birth; you should have at least 3 normal, regular periods before using fertility awareness apps or other methods.
