Is Implantation bleeding a concern?

In the case of implantation bleeding vs period, implantation bleeding happens when the embryo attaches to the uterine wall. So, it should not be a concern, either for the mother or the embryo. However, if you start experiencing heavy bleeding and the length also increases, immediately contact your healthcare provider.

It is very common for a woman to bleed during their first trimester. Almost one-fourth of women who are pregnant bleed during the first part of their pregnancy.

When to take a pregnancy test?

When you are not sure whether it is implantation bleeding or period, it is best to take a pregnancy test. A pregnancy test can be done using a test kit at home. You can even book a lab blood test for testing pregnancy.

In the pregnancy test, the level of human chorionic gonadotropin (hCG) hormone in your blood is tested. It is produced by the placenta to nourish the growing embryo. High hCG indicates that you are pregnant.

You can take the test during the period of implantation bleeding. However, there are chances that the result may come negative. The reason is implantation is a very early stage, and there might not be a release of a high amount of hCG. If you still experience pregnancy symptoms, take the test after 4 to 7 days again.

If the blood does not stop or there is heavy flow, then it can be concerning. So, when should you visit your doctor? What might the blood indicate?

Most of the time, it is nothing concerning. It might indicate that the cervix is sensitive and cause bleeding during a pelvic examination or even sex. However, heavy bleeding can indicate something serious.

● Ectopic pregnancy- Bleeding even after a positive pregnancy test can sometimes be a sign of ectopic pregnancy. It is very rare. It happens in 1 to 2 per cent of pregnancies. In this, the egg is fertilized outside the uterus.
● Early miscarriage- Blood can be a sign of early miscarriage. It can happen within 20 weeks of getting pregnant. This complication is quite common. Almost 80 per cent of miscarriage occurs in the first trimester.
● Molar Pregnancy- In this, the implanted egg forms a mass of tissue instead of a baby.
● Subchorionic haemorrhage- In this, the bleeding happens when the placenta detaches itself from the original site of implantation.

In case you see bleeding even after you test positive for pregnancy, immediately contact your healthcare provider or a fertility expert. It might be something serious. It should not be, but what if it is a miscarriage or any other serious complication? Do not get disheartened. There are many other ways you can become a parent.
