When to Take a Pregnancy Test: A Days Past Ovulation (DPO) Chart
The two-week wait can make a few days feel very long. If you’ve been counting dates, checking symptoms or wondering whether it’s time to test, you’re not alone. This guide will help you choose a testing day and understand what an early result can and can’t tell you. You don’t have to work it all out from one test.

What DPO Means
DPO means days past ovulation: 1 DPO is the day after ovulation. If you know when you ovulated, this can be a helpful way to follow your testing timeline. An ovulation test detects an LH surge, which suggests ovulation may be approaching; it does not confirm the exact day you ovulated.
You can track your cycle and ovulation tests in the Cubtale app, keeping test photos, symptoms and notes together while you wait. Our guide to reading ovulation test strips explains how to recognize an LH surge. App predictions and LH tests estimate timing, so your DPO count may still be a little uncertain.
Why You Cannot Test Right After Ovulation
A pregnancy test looks for hCG, a hormone made only after a fertilized egg implants in the uterus. Implantation usually happens 6 to 12 days after ovulation. After that, hCG roughly doubles every 2 to 3 days. So the test needs time, first for implantation and then for hCG to rise above the level the test can detect.
DPO Pregnancy Test Chart
| Days past ovulation | What is happening | What to expect from a test |
|---|---|---|
| 1 to 6 DPO | The egg is fertilized (if it is going to be) and travels to the uterus. No hCG yet. | Usually too early for a urine test to detect a pregnancy from this cycle. A negative result cannot rule it out. |
| 7 to 9 DPO | Implantation may begin. hCG, if any, is very low. | Usually too early for a reliable answer. A negative result does not rule out pregnancy. |
| 10 DPO | Implantation has happened in many pregnancies. hCG is starting to rise. | Some sensitive early tests may show a very faint line. Many pregnant people will still see a negative. |
| 11 to 12 DPO | hCG keeps rising. | A faint positive becomes more likely with a sensitive test and first-morning urine. |
| 13 to 14 DPO | Around the day of your expected period for many people. | A good time to test. Still, the FDA notes 10 to 20 in 100 pregnant women will not get a positive on the first day of a missed period. |
| 15 to 21 DPO | hCG is higher. | Results are much more reliable. If your period is late and the test is negative, retest or talk to your doctor. |
Days are approximate. Implantation timing and hCG levels vary from person to person, and between pregnancies.
10 DPO: Is It Too Early to Take a Pregnancy Test?
At 10 DPO, it may still be too early for a clear answer. Implantation timing varies, and hCG may not yet be high enough for your test to detect. If you see a faint colored line within the instructed reading window and the control indicator is present, follow your test’s result diagram. If the result is negative or unclear, try again in a few days or when your period is due. Our guide to faint lines explains what a light line can mean.
12 DPO: What If Your Pregnancy Test Is Negative?
By 12 DPO, more pregnancies will show a line on a sensitive test, but many will not yet. If the line is faint, check whether it has color. A gray streak that appeared after the reading time may be an evaporation line.
14 DPO and Later: When to Test Again
For many people, 14 DPO is around when their period is due, so it’s a reasonable time to test. An early negative can still leave you wondering. Follow your test’s instructions and try again in a few days if your period hasn’t arrived. If a second test is negative and your period is still missing, contact your healthcare provider. The FDA notes that waiting 1 to 2 weeks after a missed period gives the most reliable results; you don’t need to wait that long to take an initial test.
If You Do Not Know When You Ovulated
You don’t need a perfect DPO count to choose a testing day. If you know when your period is due, follow your test’s instructions and test from that date. If you don’t know when it’s due, NHS guidance is to test at least 21 days after the last time you had unprotected sex. If a second test is negative and your period still hasn’t arrived, contact your healthcare provider.
Tips for Testing Early
- Use first-morning urine, which is more concentrated.
- Check the box for the hCG level the test detects. Lower numbers mean a more sensitive test.
- Avoid drinking a lot of fluid before testing.
- Set a timer and read within the window, then take a photo.
- If you test early and get a negative or unclear result, wait a few days before trying again, following your test’s instructions. You don’t need to test every few hours. Line darkness cannot tell you whether a pregnancy is healthy.
If your result is positive, contact your healthcare provider to discuss next steps. When you’re ready, our due date calculator can help you estimate when your baby may arrive.

Frequently Asked Questions
How many days past ovulation can you get a positive pregnancy test?
hCG can usually be detected 12 to 15 days after ovulation. Some people see a faint positive a little earlier, around 10 or 11 DPO, with a sensitive test.
Is 10 DPO too early to test?
It is early. Many pregnant people get a negative at 10 DPO. If you test and it is negative, try again in 2 days or wait until your period is due.
Can I test before a missed period?
Yes, but results are less reliable. A positive is usually meaningful; a negative may just mean it is too early.
What time of day should I take a pregnancy test?
First thing in the morning is best, especially when testing early, because urine is more concentrated.
How do I know if the line on my test is positive?
A positive line has color and appears within the reading time, even if it is faint. You can upload a photo to the Pregnancy Test Reader for a second read.
