If the pregnancy took place the 24th of June when is the baby supposed to be born?

Answer 1

It is important to realize that babies are really "due" anytime between 38 and 42 weeks after the first day of your last menstrual period, assuming you ovulate on Day 14 of your menstrual cycle. So you really should be thinking more in terms of a "due month".

That said, the typical way of estimating a baby's due date is usually Naegle's rule. You use the first day of your last menstrual period, add a year, subtract 3 months and add 7 days. I'm not sure what you mean by "pregnancy took place on the 24th of June". If you mean that this is the day you had intercourse leading to this pregnancy, it could have been anywhere from 5 days before to 1-2 days after your ovulation.

So, assuming you ovulated on June 24, 2009 and you have a "typical" 28 day cycle, we could use June 10th as the first day of your last menstrual period. We would then add one year (June 24, 2010), subtract 3 months (March 24, 2010) and add 7 days (March 31, 2010). Your due date would then be March 31, 2010.

It is typical for women with regular prenatal care to have their due dates confirmed through a first trimester ultrasound. Early ultrasounds are much more accurate at dating a pregnancy than later ultrasounds.

Good luck!
