You can't predict the exact event precisely. Usually, estimates are given within about a week, sometimes even two. Typically, ovulation is considered to occur around the middle of the cycle, assuming a 28-day cycle, and we base calculations on that. However, ovulation can happen a week earlier or later, or even two weeks apart within a cycle. In theory, you could try to get a more accurate estimate using ultrasound and hCG data, especially if you had taken the hCG test at the start. But considering the variability of 1-2 weeks in ovulation timing and the fact that sperm can survive in the reproductive tract for up to a week, it's impossible to determine a precise date. 😄

What exactly do you need?

Masha Understand when conception occurred 😊

The difference is minimal; everyone has similar timing. 😊 The conception most likely occurred about 14-16 days before the missed period.

Eremeeva Tatyana Thank you very much for your response! ☺️

Why do you want to know when it happened? For what purpose? To mark the conception day? 😊
Nobody can tell you the exact date. Your ovulation could have occurred in the middle of your cycle or shifted. Sperm can stay in the reproductive tract for up to a week before fertilizing the egg, or it could happen on the same day. Due dates are estimated based on the size of the fetus, which can grow slightly faster or slower than average. That’s perfectly normal. A due date doesn’t mean you'll give birth exactly on that day.
