Watch out for any signs of discomfort such as excessive vaginal bleeding, spotting, cramps in the lower abdomen, lower back pain or an increase in pelvic pressure. These could be signs of preterm labor and must be reported to your doctor immediately.
It is best that your baby is born post week 37. This way s/he will be considered full term and be less prone to health concerns. A baby born prior to week 37 will need a longer stay at the hospital and this could stress the entire family.
