All You Need to Know About 15 DPO

So, you’ve reached 15 DPO (that’s 15 days past ovulation if you’re just joining us). If you have a regular(ish) 28-day cycle, the nail-biting Two Week Wait (TWW) is now over. And… still no period.

15 DPO

You’re nervous. You’re excited.

And you’re bursting with questions: Will a 15 DPO pregnancy test be positive? Was that nausea I just felt? Where did I put that baby name book?

We get it. Let’s get stuck into what you can expect at this early milestone.

And if you’re confused by all the acronyms, here’s a glossary.

What is happening at 15 DPO?

Every woman TTC (trying to conceive) goes through their own unique experience.

Still, that doesn’t mean we can’t give you the lowdown on the general patterns to look out for.

15 DPO may seem early, but your body is no procrastinator!

If there is a baby in there, they’ve been implanted in your uterine lining for about a week already.

Their cells are steadily dividing, and some have started burrowing deeper into the lining to start forming the placenta.

Around them, the amniotic sac is forming and they’re getting ready to build all the different systems they’re going to need in the big wide world.

How many DPO is considered late?

15 DPO is technically the first day that your period is considered late.

Although there aren’t many women who have a clockwork four-week cycle, doctors work on the assumption that you ovulate between days 12 and 14 of your cycle.

After that, there’s the luteal phase, during which your body gears itself up to nurture a possible pregnancy.

This can last anything between 10 and 17 days, but the “normal” length is 14 days.

That means that by the time you’ve got to 15 DPO, you’re on cycle day 29 — and officially one day overdue for your period.

Can you get a positive pregnancy test at 15 DPO?

By 15 DPO, your body’s recognized that an egg has implanted, and has started producing the hormone hCG (human chorionic gonadotropin).

This is what pregnancy tests will test to determine whether you’re pregnant.

Most home tests can pick up even tiny levels of hCG. So by 15 DPO, a home pregnancy test is quite likely to give you a reliable result —which might mean a BFP (Big Fat Positive) if you’re pregnant.

When taking the test, follow the instructions as best you can. Usually this means:

  • Testing first thing in the morning when the hormones in your pee are most concentrated
  • Waiting for the right number of minutes before you read the result
  • Making sure that the test is in date and was stored correctly

Remember that even if the line is really faint, it still could be a BFP.

If you test again in a few days, the line should get darker as your hCG levels rise.

If this doesn’t happen, or your 15 DPO positive pregnancy test is followed by BFNs (Big Fat Negatives), it might be worth getting a test with a healthcare provider, as there’s a chance you may have experienced an early pregnancy loss.

If the first pregnancy test result is a BFN, though, that doesn’t necessarily mean you’re not pregnant.

At 15 DPO, it’s perfectly possible that your hormone levels just aren’t quite there yet, or that you ovulated a day or two later than you thought.

Hang in there, maybe try to take your mind off things, and take a test again in a day or two if your period still hasn’t put in an appearance.

15 DPO symptoms

From as early as 7 or 8 DPO, pregnancy hormones can cause some early symptoms. The most common are:

  • Fatigue
  • Sore boobs
  • Changes to your sense of smell
  • Needing extra breaks to run to the bathroom
  • New cravings and revulsions to different foods
  • Nausea, especially when your stomach is empty
  • Dizziness
  • Various cramps, aches, and pains in your back or pelvis

At 15 DPO, spotting can also occur. At this stage, this can still be late implantation bleeding.

15 DPO and no symptoms?

At 15 DPO (if you’re pregnant) you might have early symptoms — or you might be four weeks pregnant and feel completely normal.

A lot of women don’t have any symptoms at all until about six weeks in, when pregnancy nausea tends to step up.

So, if you’re symptom-free, breathe out.

There’s no link between how severe your symptoms are and how healthy your baby is.

So what are you waiting for?

Go and get a test or, if you’ve already got your 15 DPO BFP, congratulations!
