How Many Days After Unprotected Sex Can I Take a Pregnancy Test?

Person Holding a Pregnancy Test

The best time to take a pregnancy test after unprotected sex is on the first day of your missed period. This gives you the most accurate result.

Pregnancy tests detect a hormone called hCG in your urine or bloodstream. It takes about 10 days for sperm and an egg to meet, grow and then implant into the uterus.

Urine Tests

If you’re worried about getting pregnant after unprotected sex, it’s important to know when the best time to take a pregnancy test is. The optimum time frame depends on the date of your last period, when you think you ovulated, and the type of test you use.

Generally speaking, most doctors recommend waiting until you miss your period to take a home pregnancy test. This way, the level of hCG (human chorionic gonadotropin) in your body will have reached its peak. Testing before this point can result in a false negative since the test may not detect the hormone in sufficient quantities.

At-home urine tests are the most common method of finding out if you’re pregnant. They’re relatively inexpensive and very easy to use. These tests typically involve peeing directly onto the test strip or using a kit that involves dipping the stick in your urine. These tests are fairly accurate and can give you results within minutes.

However, if you want to be absolutely sure that you’re pregnant, a blood test is the way to go. This type of test can be performed as early as three days after unprotected sex and is the most accurate option for detecting hCG levels.

Blood Tests

Many people may wonder how soon after unprotected sex can they take a blood test. These tests measure the levels of hCG in a person’s blood. They are typically conducted in a doctor’s office or a clinic. The results are more accurate than a home pregnancy test and may show up sooner. For best results, these tests should be performed first thing in the morning and before drinking any fluids.

For most women, the earliest a hCG blood test can be taken is six days after unprotected sex. This is because it can take several days for the sperm and egg to meet and fuse into one cell, which can be detected by a blood test. Blood tests can also work a bit earlier than urine tests because they measure hCG directly.

The main reason why it can be difficult to know when you can take a pregnancy test after unprotected sex is because conception doesn’t happen right away. It can take several days for the sperm to meet up with an egg, and then more time for the fertilized egg to implant in the uterus.

For this reason, it’s important to wait until the first day of a missed period or 21 days after unprotected sex before taking a pregnancy test. If you’re not able to wait that long, there are other options like the “morning-after pill,” which can work from 72 hours after sex to five days before a missed period.

Digital Tests

Pregnancy tests work by measuring a hormone called human chorionic gonadotropin (hCG), which is produced when an egg becomes fertilized. If you are pregnant, the hCG will show up in your urine or blood.

Most experts recommend waiting until you miss your period to take a pregnancy test. The reason for this is that the fertilized egg needs a few days to grow and implant itself in the uterus before the hCG shows up in your pee or blood. Taking a test before this time can give false results.

However, some very sensitive pregnancy tests can detect hCG in your urine as early as seven days after unprotected sex. These are usually available at Planned Parenthood or other health care providers, but they may require you to visit a clinic.

Some pregnancy tests can also detect hCG in your blood, but they are more expensive and less widely available than those that measure your urine. These are often used by doctors to diagnose early pregnancy and have a higher accuracy rate than urine tests.

If you are concerned about becoming pregnant and don’t want to wait to find out if you are, you can use emergency contraception such as the morning-after pill (Plan B or Ella). It’s important to talk with your doctor before you start using this type of medication.

Other Tests

Generally speaking, the best time to take a pregnancy test after unprotected sex is on or around your first missed period. The reason behind this is that a pregnancy test only detects the hormone hCG in urine once the fertilized egg implants itself in the uterus (known as implantation). Taking a test before implantation occurs may result in a false negative or a positive test, depending on your specific menstrual cycle and the type of test used.

The earliest a pregnancy test can be taken is actually the day before you expect your period to start, but this can be misleading since conception doesn’t occur right after sex. It takes several days for sperm and an egg to meet and then form into a fertilized egg. From there, it takes several more days for the fertilized egg to grow and travel down into the uterus lining to implant itself.

This process can take two to three weeks, which is why many people don’t get their period the day after unprotected sex. If you don’t want to wait until your period starts or can’t, you can use emergency contraception within five days of a missed period to prevent pregnancy. In addition, Planned Parenthood centers and community clinics have lower-cost pregnancy tests available to anyone who needs them. They can also refer you to a medical professional for a more accurate test.
