How Long to Wait Between Pregnancy Tests


When you and your partner are trying to conceive it can be exciting when you go to take a pregnancy test. You hope that the test shows a positive and you can begin sharing and telling friends and family you are expecting. On the other hand, it may be disappointing when you take a pregnancy test and discover it is negative. A lot of women just “know” and feel that they are pregnant, but the pregnancy test may not show a positive right away. Taking another pregnancy test right after is not recommended and will be a waste.

Most pregnancy tests recommended you wait at least a week before testing again, so that you do not waste another pregnancy test. You want to wait for your body to build up enough hCG in your urine to show a positive pregnancy test. Your hCG hormone will double almost every 48 hours, so if you are pregnant maybe waiting 48 hours may be ideal. There is nothing wrong with testing daily besides it costing some money.

What is hCG? hCG stands for “human chorionic gonadotropin”. The only time that this hormone will ever appear in your system is after an embryo is implanted into the endometrium. Another hormone that can be tested for is the H-hCG, which stands for “hyperglycosylated human chorionic gonadotropin”. “Early” pregnancy tests test for this hormone. This hormone appears in your body shortly after fertilization.

When to take the pregnancy test is also important. A lot of women feel that if they are one day late, taking a pregnancy test will show a positive pregnancy. In some cases it may, but more than likely it will still be negative. Some women may have very regular cycles, but it is important to remember that they can vary by a few days. For example, if your cycles were about 30 days, it would be smart to test at about day 32 or day 33.

If you are trying to become pregnant, you should be tracking your cycle not only to determine when to try and get pregnant, but also to know when and if your cycle is over so you can test.

Knowing how to and the basics of your cycle is important. Tracking your cycle should be something that every woman does whether they are trying to get pregnant or not. Let us get down to the basics. When you ovulate, an egg is released from your ovary and the egg is only viable for 12 to 24 hours. Sperm can last 48 to 72 hours after sex. Using those times frames, there is a very small window for you to get pregnant. Isn’t that crazy? This is such a short period of time and it seems like some women become pregnant so quickly and easily.

After you know when you are ovulating, you will want to plan to have sex on your most fertile days. Your most fertile days are usually three days before you ovulate until the actual day you ovulate. When you have these days calculated, begin planning when you will have sex. Remember, sperm can last up to 48 hours to 72 hours after sex, so make sure you use those time frames when calculating.

To help determine this time frame, tracking when you ovulate is important. It is also helpful in determining when to test to see if you are pregnant. There are some fertility apps available such as Kinadra or Glow. These apps can be downloaded onto your phone, so you have easy access to record what is going on with your body.

If you have a good idea on how your cycle goes (duration, days, etc.) then you probably will only need to use one pregnancy test to get a positive pregnancy show up. If at any point you are concerned you truly are pregnant and a positive is not appearing on a pregnancy test, you may want to consult your healthcare provider. They may recommend a blood test and other testing to see if there are any other problems to be concerned about.
