What exactly is the date of conception?

It’s the magical moment when sperm meets egg and the journey of new life begins!

But here’s the thing – figuring out the exact day of conception is a bit tricky. Ovulation, the release of the egg, typically happens between days 11-21 of a woman’s monthly cycle. That’s quite a wide window, isn’t it?

To add to the mystery, conception can occur within hours or up to a week after intercourse! How? Well, sperm can hang out inside a woman’s body for up to a week, patiently waiting for the egg to make its grand entrance.

How is the date of conception calculated?

It’s simple math!

For a standard 28-day cycle, subtract 266 days from your estimated due date, and voila – you’ve got your estimated date of conception.
