Pregnancy months vs. calendar months at 22 weeks
Pregnancy months are counted in two ways. Most US pregnancy charts group the 40 weeks into nine “pregnancy months” of four or five weeks each, which puts week 22 in month 5. A calendar month is about 4.35 weeks (30.44 days), so 22 weeks of calendar time is 5.1 months. Both answers are correct for what they measure; your provider will track the pregnancy in weeks.
