Pregnancy is an exciting time in your life, and you may be eagerly watching for those very early signs in weeks 1, 2, or 3. But, did you know that you’re not actually pregnant during these first couple of weeks? We know it’s a little confusing, but it’s also why you might not notice any pregnancy symptoms early on! Keep reading to better understand what’s going on in that body of yours during the first three weeks of pregnancy.
Your First Three Weeks of Pregnancy
Here’s the thing: Because of the way pregnancy is usually measured, you’re not actually pregnant during the first two weeks or so of your pregnancy. Healthcare providers calculate the length of an average pregnancy as 40 weeks, starting from the first day of your last menstrual period—this is known as the LMP dating method.
So, when you’re 1 week pregnant, you’ve only just started your period. At two weeks pregnant, you’re ovulating. And since ovulation happens about 14 days after the start of your period (assuming you have a 28-day cycle) you can’t really become pregnant until week 3 at the earliest.
It can be mind-boggling—we get it. But, for the sake of calculation, and what you and your healthcare provider will consider as 1 and 2 weeks pregnant, you’re not actually pregnant! But although at 1, 2, or 3 weeks pregnant you may not notice any of those very early signs of pregnancy, there may be a lot happening on the inside.
Will You Notice Early Signs and Symptoms When You're 1 Week Pregnant or 2 Weeks Pregnant?
Your journey through pregnancy has officially begun, but as mentioned above, you’re not actually pregnant yet. Remember that healthcare providers calculate your pregnancy as 40 weeks, or 280 days, from the start of your last period. So, if you have a typical 28-day menstrual cycle, the first two weeks are mainly just Aunt Flo doing her thing.
But after two weeks, other things start to happen.
-
One of your ovaries will release an egg around 14 days after the first day of your last period.
-
The egg will travel down one of the fallopian tubes where it may unite with sperm.
It’s worth noting that sperm can live inside your body for up to five days, and your egg has a lifespan of up to one day. This means your window of fertility (when you should have sex if you’re trying to get pregnant) is about five days before you ovulate to one day after.
What this all means is that you won’t feel any of those very early signs of pregnancy in weeks 1, 2, or possibly even 3. If you have yet to conceive, then it makes sense that you wouldn’t notice anything!
|
In Summary You’re not actually pregnant during the first weeks of a typical 40-week pregnancy! This is because pregnancy is usually calculated starting from the first date of your last menstrual cycle. Assuming you have a typical 28-day cycle, you won’t ovulate until week 3 of pregnancy. |
What Are the Signs and Symptoms When You're 3 Weeks Pregnant?
When you’re 1 week “pregnant,” you haven’t conceived yet, and so there’s not much going on. That can change by the time you’re three weeks pregnant. Your belly can be a hive of activity, though you may not be able to tell.
-
If the sperm and egg find each other, they’ll join up in a fallopian tube to create a single cell called a zygote in a process called fertilization.
-
The zygote carries chromosomes from the mother and father and sets the first building blocks of your future baby’s genetic makeup.
-
The zygote then moves down the fallopian tube and toward the uterus as it starts dividing into a larger group of cells.
Although there’s more activity in your third week of pregnancy, will you feel anything? Probably not. However, read on to learn a bit more about those typical early symptoms of pregnancy and when you might notice them.
|
In Summary Because of the way healthcare providers calculate pregnancy, you might not be pregnant until 3 weeks. Therefore, it’s very unlikely that you’ll notice any of those early signs of pregnancy during weeks 1 and 2, or even in week 3. |
Will You Notice Any Pregnancy Symptoms During Weeks 1, 2, or 3?
During weeks one, two, or three, you may not even suspect you’re pregnant and you might not notice any pregnancy symptoms at all, as it’s still very early. Don’t worry—this is common (and you might not have even conceived until 3 weeks pregnant).
Missing a period is often the first clue that you may be pregnant, and around the time you miss a period—or a little later—you may start noticing those very early pregnancy symptoms.
One common early pregnancy symptom is implantation bleeding, which is light spotting that occurs when the tiny ball of cells (now known not as a zygote, but as a blastocyst) attaches to the uterine lining. Not everyone experiences it, but this light bleeding is normal and can sometimes be mistaken for menstrual blood. It usually happens 10 to 14 days after conception.
Other signs of pregnancy in the first month can include
-
bloating
-
gas
-
fatigue
-
moodiness
-
frequent urination.
Morning sickness is another common symptom of early pregnancy, but it usually crops up between weeks 4 and 9. Now that you know these early signs of pregnancy, take our quiz to test your knowledge!

In Summary Although you might not notice anything very early on, there are some common signs of pregnancy that may occur in your first month. They include a missed period, implantation bleeding (light spotting), bloating, gas, fatigue, breast tenderness, moodiness, and frequent urination. |
When Can You Confirm Your Pregnancy?
If you think you might be pregnant because you missed your period or are experiencing some of the early symptoms of pregnancy listed above, you can take a home pregnancy test.
These tests can confirm a pregnancy by checking your urine for the presence of a hormone called hCG.
|
Tip If you take a home pregnancy test too early, there may not be enough of the hCG hormone in your urine. Check the packaging on the test you buy for information on when to take it. Some tests require waiting until at least the first day of your missed period, but others can detect lower levels of hCG and may be accurate a little earlier on. |
If you think you may be pregnant, but the test says otherwise, test again after a few more days or speak to your healthcare provider. You can also ask your provider to confirm your pregnancy with a blood test.
