When Did I conceive? Calculate Your Date

You can find almost anything on the internet these days, but if you’re asking yourself, “When did I conceive?” or “How far along am I?” using a due date or conception calculator can only give you a ballpark idea. It won’t provide the specifics you need to make informed choices about your pregnancy.


It’s also essential to verify if you're truly pregnant. Home pregnancy tests, while significantly more reliable than they used to be, can only confirm a pregnancy. They cannot verify that the pregnancy is viable.


The only way to get a clear picture is through an ultrasound. This scan will give you a more accurate estimate of how far along you are, your likely conception date, due date, and even the viability of your pregnancy. Ultrasound exams provide detailed images and measurements of your baby that can help pinpoint your gestational age and conception timeline.


We offer no-cost ultrasounds to those who test positive through one of our laboratory-grade pregnancy tests.


HOW TO ESTIMATE YOUR CONCEPTION DATE

If you're looking for an idea of when conception occurred before scheduling an ultrasound, there are a few methods to consider:

  1. Ovulation


    One way to guess when you conceived is by pinpointing your ovulation date. Typically, ovulation happens about two weeks after your last menstrual period and lasts around 24 hours. Since conception usually occurs around this time, tracking your ovulation can give you a rough idea of when you became pregnant.


However, this isn’t always 100% reliable. Not every woman has a regular cycle. Some women have irregular periods, or ovulation may occur earlier or later than expected. So, using ovulation alone to figure out your conception date can be tricky.


  1. Intercourse


    Another method is to track the last time you had sex. But here's the catch—this isn’t foolproof. Conception doesn’t happen immediately after intercourse. Sperm can survive for up to 5 days in your body, which means it’s tough to nail down exactly when you conceived, especially if you had multiple sexual partners around the time of ovulation. Plus, even if you or your partner used contraception, there's always a small chance it didn’t work as intended.


  2. Ultrasound


    The most reliable way to determine your conception date is by getting an ultrasound. Early ultrasounds (especially during the first trimester) are incredibly accurate because babies grow at a similar rate during that time. By getting an ultrasound, you’ll be able to estimate your conception date and your baby’s age more accurately than relying on your cycle or sexual activity.


We offer free ultrasounds to help you confirm your pregnancy and pinpoint your conception timeline. This can be especially helpful for those with irregular cycles or who can’t remember the exact date of their last period.
