Questions in a pregnancy health history
To figure out how pregnant the woman is now, take the first
day of the last monthly bleeding and count the number of weeks
that have passed between that day and this visit.

By the end of May
she had been
pregnant for
4 weeks, and...
...by the end
of June,
8 weeks.
Today is July 12th,
so she is
9 weeks and 4 days
pregnant, or a
little more than
2 months.
Using the moon
If you do not use calendars, you can find the due date using the moon. If a
woman’s monthly bleeding is usually about one moon (4 weeks) apart, the baby
is due 10 moons after the first day of her last monthly bleeding. If a woman’s
monthly bleeding started on a quarter moon, the baby is due 10 quarter moons later.
If her bleeding started on a new moon, the baby is due 10 new moons later, and so on.
For example:
If her bleeding started
on the full moon,
she probably got
pregnant on the
new moon.
The baby is due
10 lunar months after
the first day of her last
monthly bleeding —
in this case,
10 full moons after
the first day of her last
monthly bleeding.
