Implantation bleeding: How soon after implantation can I test?

Implantation bleeding is vaginal bleeding that results from a fertilized egg attaching to the wall of the uterus. It occurs in 1 in 4 pregnancies, typically, between 10 and 14 days after ovulation. Although implantation bleeding is one of the earliest signs of pregnancy, there are also other things that can cause spotting or bleeding around this time. Thus, the only way to confirm pregnancy is to take a timely pregnancy test.

How soon after implantation can I test? Though it can feel tempting to test right away, this is often too early to get an accurate result because tests detect the hormone hCG that builds up over time. Ideally, you should wait until you miss your next period and do a test starting from the first day of a missed period.

If you are actively trying to conceive, you are probably doing everything to boost your chances. Most likely, you are tracking your ovulation and are looking out for the earliest pregnancy signs to know when you achieve the desired pregnancy.

If all that sounds like you, we bet that you’ve already heard the term “implantation bleeding.” Taking place when a fertilized egg attaches to the uterine lining, this bleeding can signal the official beginning of your pregnancy, so when you notice it, you might instantly get a question – How soon after implantation can I test?

Although your desire to find out whether you’re pregnant or not as early as possible is easy to understand, taking a test too early can result in a false-negative result. Your body needs time to build up the hormone hCG so that a pregnancy is shown in test results. In this article, we’ll explore when to test after implantation bleeding to help you get an accurate result.

Understanding Implantation Bleeding

If you’re asking yourself a question, “How soon after implantation can I test,” it’s important that you understand what implantation bleeding is and how to distinguish it first. So, let’s take it from there.

Implantation bleeding is vaginal bleeding that takes place during implantation. At this time, a fertilized egg attaches itself to the lining of the uterus, which can cause bleeding due to physical damage to the lining.

According to different figures, implantation bleeding occurs in roughly 1 in 4 pregnancies. It usually takes place around 10 to 14 days after ovulation. Although it occurs at about the same time when you would have your period (if conception didn’t happen), it’s possible to distinguish implantation bleeding from menstruation by the following features:

• Unlike period bleeding, implantation bleeding is usually much lighter in flow or spotty. Sometimes, it can be heavy, resembling the start or end of menstruation.
• It can be pink or brown in color, unlike period bleeding, which is usually bright or dark red.
• It can last for just a couple of hours to several days.

If the conception was successful, you can experience implantation bleeding along with other early pregnancy signs, such as nausea, breast tenderness, mood swings, light cramping, etc.

How soon after implantation can I test?

When trying to conceive, the two-week wait that lasts from the moment you ovulate until you get a positive pregnancy test result can feel unbearable. Naturally, you can have the urge to do a pregnancy test as soon as you can, for example, right when you notice implantation bleeding. However, it’s important to remember that doing a test too early is one of the most common reasons for getting a false-negative result. That’s why you have to know when it’s just the right time to do it.

So, how many days after implantation bleeding can you test? If you notice light spotting that doesn’t feel like your period, it could be implantation bleeding, but not necessarily. Although there are certain characteristics that can help you distinguish implantation bleeding from a period, it’s not possible to be 100% sure that spotting is indeed caused by implantation. The truth is that light spotting can be caused by a variety of things, including progesterone and other hormone fluctuations, and other factors. And, sometimes, doing a test right after noticing spotting might be too early to get an accurate result.

In order to answer the question of when to take a pregnancy test after implantation bleeding, you need to better understand the entire timeline of getting pregnant. Let’s break it down for an average, 28-day menstrual cycle:

• If your cycle lasts for 28 days, you should have ovulation around day 14. However, it’s worth noting that female cycles aren’t steady and can vary in length from month to month. This means that the day of ovulation can change as well. And the best way to know when exactly you ovulate is by tracking ovulation and using ovulation kits.
• When your ovaries release a mature egg in ovulation, it can be fertilized for about 12 to 24 hours. This doesn’t necessarily mean that you have to have sex within this window. Sperm survives inside a female body and maintains its ability to fertilize an egg for about 4-5 days. That is, having sex at any time during your fertile window can lead to fertilization.
• If the egg is fertilized, it will then travel down the fallopian tubes. It usually takes 3-4 days for it to reach the uterus.
• When it reaches the uterus, the egg needs to attach to its walls. This is the point when you can experience implantation bleeding. Usually, it takes place around 10 to 14 days after ovulation, although it can happen as early as 6 days after ovulation.
• After implantation occurs, your pregnancy officially begins. However, testing right now can be too early. The thing is that an implanted egg starts to release human chorionic gonadotropin (hCG). This is the hormone that supports your pregnancy and also the hormone that pregnancy tests detect. Right after implantation, its levels are still low, and they need to build up in order to be detected by a test. This is the reason why doing a pregnancy test 1 day after implantation bleeding can lead to a false negative.

How Much Time Is Needed for hCG to Build Up After Implantation?

So, how soon after implantation bleeding can I test? To find the answer, you also need to understand the production of hCG apart from understanding the pregnancy timeline.

When the egg implants, it starts producing hCG immediately. In a healthy pregnancy, the levels of this hormone double every 48-72 hours. They usually become sufficient to be detected by a test around 3-4 days after implantation.

How Many Days After Implantation Bleeding Can You Test and Get a Positive Result?

Given the fact that it’s impossible to be 100% positive that the spotting you’ve faced was caused by implantation, and also the fact that testing right after implantation might be too early to detect a pregnancy, the universal advice is to wait until your next period. Most at-home pregnancy tests promise an accurate result as soon as one day after you’ve missed your period.

So, if you are not sure that what you have is implantation bleeding, you should wait with a test until the second day of your expected period. If it doesn’t come, you can test and expect a positive result.

Detecting Pregnancy Beyond Tests: When Do Early Pregnancy Signs Show After Implantation?

Apart from a positive test result, you can confirm that you’re pregnant by paying attention to early pregnancy symptoms, such as:

• Nausea
• Breast swelling and tenderness
• Bloating
• Mood swings

Since every pregnancy is different, these symptoms can start showing at any time after implantation. Some women can notice them as early as 1-2 weeks after conception, which is close to the time when you can experience implantation bleeding. However, others may not have any early pregnancy signs until 4-5 weeks.

If you notice the aforementioned symptoms early, before you miss your expected period, it’s also important to remember that the same symptoms are typical for premenstrual syndrome (PMS). That is, they don’t always mean that you're pregnant. So, the only way to tell for sure is to take a pregnancy test.
