Complications During Pregnancy & Birth
Ectopic Pregnancy-the pregnancy tissue or embryo becomes implanted somewhere in the abdomen other than the uterus. The embryo might die and often must be removed by surgery.Miscarriage-embryo is expelled from the uterus before it is sufficiently developed. Caused by genetic defect, illness in the mother, drugs the mother has taken, or other factors. Miscarriage usually occurs during first three months of pregnancy.
Complications During Pregnancy & Birth
Premature Birth-a baby is born before it is completely developed. A baby that is born before the 37thweek of pregnancy is considered premature. Premature babies are placed in new born intensive care where they can develop further.Cesarean Section-AKA C-section. If delivery through birth canal is considered risky for any reason, an operation is performed. An incision is made through the abdomen and uterus and the baby is removed.

This may happen if the mother isRhnegative and the baby isRhpositive. This can be avoided by giving injections which prevent the woman’s body from producing theRhantibody.
