Please let me know whether it is possible to avoid conception after sex that is assumed to be unsafe, because of some leakage in the condom. No pills were taken before sex, only condom was used for contraception, but some leakage noticed from back side that is doubtful to enter in the vagina. Kindly share your knowledge if something is possible to avoid pregnancy. As previous delivery was cesarean only six months before & atleast 2 years gap is necessary for safety of next delivery.
