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

392 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.

Women often experience what is known as implantation bleeding 10-14 days after conception. The implantation bleeding can be mistaken for a period, particularly with women who tend to have light menstrual flows.
