How do you determine the date of conception if are 12 weeks and 2 days pregnant?

To determine the date of conception if you are 12 weeks and 2 days pregnant, you can subtract the number of weeks from the first day of your last menstrual period (LMP).

Since a pregnancy is typically calculated from the first day of your last menstrual period, you would need to subtract 12 weeks and 2 days from the first day of your last period to estimate the date of conception.

For example, if the first day of your last menstrual period was January 1, 2023, you would subtract 12 weeks and 2 days from that date, which would give you an estimated date of conception of October 5, 2022.

It's important to note that this is just an estimate, and the exact date of conception can vary from person to person. Your healthcare provider can provide you with a more accurate estimate of your conception date based on your individual circumstances.
