Can I still be pregnant even though my home pregnancy test was negative?

A repeatedly negative pregnancy test and a missed period typically mean that you are not pregnant. A negative pregnancy test a week or more after your missed period indicates that your chance of being pregnant is less than 1-2%. A positive pregnancy test usually means that you are pregnant.

However, sometimes a negative pregnancy test after a missed period could still mean you are pregnant:

  • Maybe you miscalculated when your period was due.
  • Maybe you tested too soon and there is not enough hCG (hormone that indicates pregnancy) found when you tested.
  • You may need to wait about a week, and then retest.

hCG doubles about every 48 hours in early pregnancy. A home pregnancy test that is negative on Monday may likely be positive on Wednesday. And if it's positive with first morning urine, later on in the day, when the urine is more diluted, it could test negative. It is also important to remember that despite the advances in urine home pregnancy tests, blood tests are still considered the best at detecting early pregnancy.

The timing of a positive pregnancy test depends on implantation. If you are pregnant, a urine pregnancy test is not expected to be positive until 3-4 days after implantation (at the very earliest), which is about 10 days after ovulation/fertilization, and 4 days before the next period. About 51% of pregnant women have a positive pregnancy test two days before their next expected period.

Data is based on the fact that in each menstrual cycle there is an about 25% chance of getting pregnant as well as a scientific study published by Wilcox in JAMA.

Your chance of getting pregnant each month may be different depending on your age, certain medical issues, whether you ovulate or not, and if you are trying to get pregnant with IVF or other fertility medications.

Besides being pregnant, the next reason for missing your period is not ovulating (anovulation). That's why it is essential for every woman who is trying to conceive to chart her fertility and to find out if ovulation is occuring in each cycle. Knowing if and when you ovulated usually removes any confusion you may have if your period is late. Start charting ovulation and calculating your fertility nowYou might also use a Fertility Monitor for this purpose, there is even one electronic monitor that can confirm if and when ovulation took place. Doing this will help you find out if you ovulated, whether you are fertile, and it will let you know early on if you are pregnant.

If you know you ovulated and your period hasn't come 15+ DPO, then there could be only one reason: you are pregnant!
