When is implantation bleeding happens

After dividing into about cells, the egg becomes what is known as a blastocyst. The uterine lining has many blood vessels, so when the fertilized egg blastocyst pushes into the lining, bleeding can occur. This blood will exit through your cervix, just like menstrual flow. Implantation bleeding is one of the earliest signs of pregnancy and occurs around the same time you would be expecting your period. Since these two causes of bleeding can be confused, the best way to know for sure if you are pregnant is by taking a pregnancy test.

If you are pregnant, your body will increase human chorionic gonadotropin hCG production, which a test can detect. However, there are differences between menstrual blood flow and implantation bleeding. Some signs of implantation bleeding are:. Implantation bleeding is normal and not a risk factor. If bleeding occurs more than a few days after you expected to get your period, it will not likely be implantation bleeding.

If the bleeding is heavy, constant, or lasts for several days, it is almost certainly not from implantation and should immediately be checked by a healthcare provider.

Bleeding when suspecting a pregnancy can be alarming, but implantation bleeding is a common and normal early pregnancy sign. It may be difficult to tell if the bleeding you experience is from implantation, your period, or another cause.

Be sure to tell your healthcare provider about any bleeding you experience if you believe you may be pregnant, and seek emergency care if you experience abnormal heavy bleeding or pain if you know you are pregnant. Implantation—when a fertilized egg attaches itself to the uterine lining—typically occurs six to 12 days after conception. In a typical day cycle, implantation bleeding can occur between days 20 and Implantation bleeding is typically light pink to rust-colored discharge, spotting, or light bleeding.

It is often accompanied by light cramping and possibly headache, nausea, lower backache, mood changes, and breast tenderness. Period blood tends to be heavier, darker in color, and last longer than implantation bleeding. Implantation bleeding can last for a few hours or a day or two. It is commonly very light and can be constant or start and stop on and off for a few days.

The blood from implantation is more of a pinkish or brown color, rather than a bright red some women normally see during a period. You may notice implantation bleeding around 10 to 14 days after conception, when a fertilized egg becomes attached to the lining of your uterus. Keep in mind that conception may not occur on the same day you had sex.

You can take a home pregnancy test during implantation bleeding. Keep in mind that the pregnancy hormone human chorionic gonadotropin or hCG that pregnancy tests detect only starts being produced in your body the moment the fertilized egg is implanted in the uterus — which is the trigger for implantation bleeding.

If you experience heavy bleeding or clotting, see your doctor right away. This may be a sign of an early miscarriage.

The color and consistency of implantation bleeding may vary from person to person and pregnancy to pregnancy. But if you think you might be pregnant, there are other symptoms that you can watch for. Frequent urination, fatigue, and nausea are some of the earliest pregnancy symptoms.

Your breasts may also become tender or swollen due to the hormonal changes that occur shortly after conception. One of the most reliable symptoms is a missed menstrual period. Pregnancy test makers claim home pregnancy tests are up to 99 percent accurate. Tests may pick up the pregnancy hormone human chorionic gonadotropin hCG as soon as the first day of your missed period, sometimes earlier. This hormone doubles in concentration every two or three days in early pregnancy.

You may consider testing if your period is late or you have many early pregnancy signs. For the most reliable reading, consider waiting a week past when your period should have started. Concentrations of hCG reach the blood before the urine, so a blood test may give a positive result sooner than a urine test.

If you do get a positive home pregnancy test, make an appointment with your doctor. They can confirm your test result and discuss your options for family planning. This may mean navigating prenatal care or discussing choices.
