While pinpointing the exact moment of conception isn’t possible, understanding your body’s rhythms and cycles can help you estimate when it likely occurred.
What Date Did I Conceive?
Whether you’re in the early stages of pregnancy or further along, a little math can help you approximate when conception happened.
Typically, ovulation—the time when your body is most likely to conceive—occurs about two weeks after the start of your last period. Most women ovulate for about two to three days during each menstrual cycle, which is when conception is most likely to occur.

To estimate your conception date, start by counting the days since the beginning of your last period to identify your ovulation window. Free online calculators can simplify this process, or you can text us at (815) 912-0212 for assistance.
Keep in mind that this is just an estimate. Menstrual cycles and ovulation windows vary from person to person. Some women ovulate earlier, later, or for longer periods than average.
It’s also possible to conceive from intercourse that occurs before ovulation begins. Sperm can survive inside the body for up to five days, meaning it can still fertilize an egg if ovulation happens shortly after intercourse.1, 2

Conception Date from Ultrasound
Another method for determining your conception date is through an ultrasound. Since fetuses grow at a relatively consistent rate, their age can be measured, allowing for a more precise estimate of when conception occurred compared to using an ovulation calculator.
An ultrasound not only provides an estimate of your conception date but also helps confirm the health and viability of the pregnancy. It can ensure that the pregnancy is progressing normally, ruling out complications like miscarriage or an ectopic pregnancy.3
While you can get an ultrasound at your OB-GYN office, this often involves paperwork and billing. Alternatively, your local pregnancy center may offer free ultrasound services, bypassing the need for hospitals or insurance involvement. Contact Hope Center to see if you qualify for a free limited, diagnostic ultrasound.
