When Did I Get Pregnant?

"The good news is that you don't have to try and figure any to this out on your own." 

When did I get pregnant?

Did you just get an unexpected positive pregnancy test? And now you’re asking yourself, when did that happen?

There is really no way to determine exactly when you conceived but there are a few ways you can get an estimated time frame, which can be helpful.

Before we get started with trying to determine when you conceived it is important to note that the ovulation window is when a woman is most likely to get pregnant/conceive.  Ovulation is when the egg leaves the ovary and generally happens 14-16 days before a woman has her menstrual cycle.  So, now let’s look at ways to try and figure out when this happened.

The first is the “easiest”- and that would be if you knew when you ovulated.  If you do, yay you- most of us are not that in tune with our bodies.  Some women use an app to track ovulation or some notice physical changes such as ovulation pain, increased cervical mucus, or an increased sex drive.  If you know when you ovulated, you likely got pregnant within 3 days of that ovulation date.

The second way would be to use the first day of your last menstrual period (LMP).  If you have a typical 28-day cycle then chances are you ovulate 11-21 days from your LMP; this gives you a conception window

It is important to remember that sperm can live in the body for up to 5 days after intercourse, so if you had multiple partners within your conception window it will be very difficult to know who the father is without genetic testing.

The third and most accurate way is to have an ultrasound done to date the pregnancy.  An ultrasound can give you:

      • The estimated age of the pregnancy
      • An estimated due date
      • A more accurate conception window 

The good news is that you don’t have to try and figure out any of this on your own.  Here at Alcove Health, in Newport News, we have trained Registered Nurses available to perform limited free ultrasounds to help you answer the question,”When did I get pregnant?” Even better, all of our services are provided at no cost, in a confidential, judgment-free environment.

How Do I Calculate My Conception Date?

You can use the LMP method to estimate your conception date and your due date​

The first day of your last menstrual period, also known as LMP, will be something that doctors and nurses will discuss throughout your pregnancy.

“What’s so important about my LMP?”

Many pregnant women aren’t sure of the actual date of conception (when the egg was fertilized). Unless you are charting your cycle each month, it can be very difficult to pinpoint the specific date. If a woman knows the date of her LMP, it can give an estimated range of when she likely conceived. Why? The typical menstrual cycle (from period to period) lasts about 28 days, and ovulation usually occurs around day 14. Knowing the date of your LMP helps the doctor reasonably estimate the date you conceived and assists in determining your due date.

Are you pregnant and don’t know what to do next?  We offer free consultations and free ultrasounds, which are especially helpful when you’re unsure of your conception date. Schedule your free and confidential appointment HERE.

Common questions about your Conception Date:

    1. What if I have irregular cycles (shorter or longer than 28 days)?
    2. What if I don’t remember my LMP?

These are not uncommon questions. In fact, you might be surprised by how many women have irregular menstrual cycles or don’t remember when their last period was. If this is you, don’t panic!

Ultrasounds are another very helpful and accurate way to determine estimated due dates. Early on in pregnancy, fetal development is fairly standard. An ultrasound can determine how far along you are based on the size of the fetus.

Even if you don’t know the date of your LMP, Alcove Health can confirm your pregnancy with a lab quality pregnancy test and perform an ultrasound, at no cost, to help determine how far along you are and what your estimated due date is. You deserve medically-evidenced information to make the best decision for your reproductive health.

“When is my due date?”

You can also calculate your due date using the Last Menstrual Period method.  Knowing this information will help you know how far along you are in your pregnancy.  Schedule your free appointment to get this information and an ultrasound for free.  That’s right, we offer help and resources for your pregnancy decision and we have nothing to sell you.
