“Ten Things Nobody Tells You”
Don’t worry. We know of no conspiracy keeping you from knowing all there is to know about pregnancy. But your friends, sisters, cousins - whoever tells you what to expect with your pregnancy - often forget the little details, especially the more unpleasant ones. Furthermore, other books often gloss over this stuff, perhaps in the interest of decorum. Well, at the risk of being indecorous, we’re going to give it to you straight in this chapter.

Pregnancy Lasts Longer than Nine Months
Patients always ask, “How many
months along am I?” and we have trouble giving them a precise answer. Pregnancy
is said to last nine months, but that number isn’t exactly accurate. The
average pregnancy lasts 280 days, or 40 weeks, starting from the date of the
mother’s last menstrual period. (You think 40 weeks is a long time? Just be
glad you’re not an elephant, which has a gestation period of 22 months!) If a
month is four weeks, that calculation comes out to ten months. On the calendar,
however, most months contain four weeks plus two or three days, so nine
calendar months often do contain close to 40 weeks. Practitioners speak in
terms of weeks when measuring gestational age because it’s more accurate and
less confusing.
