Does mucus when taking Drovelis birth control pills indicate that they are ineffective?

On the basis of vaginal secretions, the effectiveness of contraceptive pills cannot be judged. The effectiveness of tablets depends on the correctness and regularity of their use. Hormonal tablets can cause changes in cervical mucus. In general, this is not a cause for concern, except when additional symptoms such as vaginal itching, burning, fever, lower abdominal pain, discharge is abundant, has an unusual or unpleasant smell. They may indicate infection of the genital tract - then contact with a gynecologist is indicated.
