All You Need to Know About 3 DPO

One thing few people tell you about TTC is how much waiting around there will be.


At 3 DPO, you might feel you still have miles to go to see if AF will BRB.

The suspense is truly nail-biting.

Don’t worry. We won’t add to it. Let’s get right to it, shall we?

What’s happening at 3 DPO?

3 DPO is near the beginning of the TWW (AKA the Two Week Wait between ovulation and your next expected period. AKA a weird stretch where time seems to slow to a snail’s pace).

When you ovulate, the egg/s you release into your fallopian tube might be fertilized by an awaiting sperm.

This has to happen pretty quickly—as in, within 24 hours of release from your ovary.

If fertilization takes place, the newly formed zygote will travel down the fallopian tube to implant itself into the lining of the uterus.

How many DPO is implantation?

Implantation happens somewhere between six and 12 DPO.

When it does, your body starts producing a hormone called hCG (or human Chorionic Gonadotropin).

hCG communicates with your body to tell it to keep producing progesterone, the hormone that does all sorts of great things during pregnancy, from helping your uterus grow to staving off contractions until the time is right.

In fact, recent research suggests that progesterone could play a role in reducing the chance of miscarriage.

Thank goodness hCG is such a great messenger.

But the wonderful work of hCG doesn’t stop there. It has another important function—it helps us detect pregnancy.

Most pregnancy tests work by looking for hCG in your urine.

To get a BFP, your hCG levels have to be above 25 mIU/mL.

That means that at 3 DPO, you’ll have to wait a bit to get a positive result. Because, if an egg has been fertilized, it’s probably still a few days away from implantation.

If you can stomach the wait, it’s not a bad idea to hang fire until after you’ve missed a period. If you’d like to take a test before that, also fine.

You can take another one later to confirm the result you get (it’s not for nothing that many pregnancy tests are sold in multipacks).

Is 3 DPO too early for pregnancy symptoms?

If you’re TTC, you’re likely itching to know the 3 DPO symptoms leading to a BFP.

You may be hyper-aware of every ache, tingle, and change. So here’s the big question:

Can you have symptoms at 3 DPO?

3 DPO is very early for symptoms.

The first bout of possible pregnancy symptoms kick off (for some) around implantation—and 3 DPO is too early for this to have happened.

So, if you’re experiencing cramping 3 DPO, it’s more likely to be because of PMS or ovulation than implantation cramping.

Also, you can be pregnant and have no symptoms at all until you’re weeks into your pregnancy.

Experiences are all so diverse.

There’s no right way to do this thing.

3 DPO symptoms

While you might not have symptoms at 3 DPO, it doesn’t mean you can’t prep yourself for the symptoms to come. Here’s some of what you might expect in the days and weeks ahead:

(If you’re TTC, never has a list of uncomfortable symptoms looked so appealing.)

The TTC experience can feel pretty isolating. Bodies are different; timelines are different; methods are different.

But you don’t have to do this alone.
