The absence or delay in menstruation is usually one of the first symptoms of pregnancy, but it isn’t a determining factor. Many women have frequent irregularities or delays in their menstrual cycle. The Chadwick sign is part of a long list of signs that occur when a woman is pregnant.

What is the Chadwick sign?

The Chadwick sign is also known as the “Jacquemier sign.” It’s characterized by a violet or dark blue tone of the vaginal mucosa and cervix. It usually appears in the fourth week of pregnancy. It’s a normal effect of local venous congestion, which occurs as a result of the increase in progesterone.

This change can be observed through a speculum during a gynecological examination. However, the appearance of the Chadwick sign doesn’t guarantee that a pregnancy exists. Color changes in the vaginal area also occur days before menstruation.

Although the Chadwick sign is considered one of the main signs of a possible pregnancy, it must be linked to other signs of pregnancy for confirmation. Some women have no symptoms of pregnancy until after 2 weeks. More than likely, these symptoms occur between 4 and 6 weeks of gestation.

Usually, the Chadwick sign remains throughout the gestation period. This can only be analyzed by a specialist through a gynecological examination.

Usually, this symptom disappears when the pregnancy ends without having to resort to any type of medical treatment. The reason why is because it’s a natural process of the physiological functioning of the body.

When should you take a pregnancy test?

There are several pregnancy tests that promise accurate results. However, specialists recommend taking one if your menstrual cycle is at least seven days late. By that time, your body will start producing the hormone hCG, which will yield a more reliable result. If you take a pregnancy test any earlier, the odds of getting a negative result increases.

If you start to experience pregnancy symptoms and think you might be pregnant, take a pregnancy test and then go to a specialist. Your symptoms may also be a sign of other medical conditions. We recommend consulting an expert.
