These polyps may follow a bout of ulcerative colitis or Crohn's disease of the colon. Although the polyps themselves are not a significant threat, having ulcerative colitis or Crohn's disease of the colon increases your overall risk of colon cancer.
This interactive Due Date Calculator will help you estimate the date your baby will arrive. Pregnancy usually lasts 280 days (40 weeks) from the first day of the woman's last menstrual period. This calculator is a general guide: every pregnancy is unique, and sometimes babies arrive sooner or later than expected. Always talk to your health care provider about your due date.
The importance of the due date to the obstetrician is emphasized when your baby chooses a date remote from the calculated due date. Worries about going beyond your due date apply as well. The tail end of the term range is 42 weeks, or two weeks after the official due date. After that, the placenta (the afterbirth responsible for nutrition and oxygen to the baby) begins dying, but your baby keeps growing as much as a half-pound a week or more.
