ELI5- Why aren’t pregnancies “discovered” earlier on?

400 views

I’m not totally sure how to ask this. So most people find out they’re pregnant between 6-8 weeks. And it’s relatively common knowledge that one does not get their period while pregnant. So my question is, how do people not find out they’re pregnant until around 6 weeks if the average menstrual cycle is 4 weeks? Ovulation occurs on, I believe, day 14 in the cycle, so shouldn’t more pregnancies be discovered at 2-3 weeks when the initial next period would occur?

ETA: thank you for the responses! My confusion began with the the whole “you’re 6 weeks pregnant” when it’s more than likely 3-4 weeks of legitimate gestation due to how doctors begin the “clock” at the end of the last menstrual cycle.

Periods vary. You don’t always get your period on the clock. They can be early, late, or even skip a cycle sometimes altogether.

If you’re not actively keeping track, it’s very easy to not notice.

If you’re seeing a doctor every day and they’re specifically checking for whether you’re pregnant, you can know earlier than that. But if you’re only telling by your cycle, then you might not know until you’re 2 months in. And unless you’re actively trying to conceive, you’re not going to be watching out for it.
