Mid-cycle bleeding, especially when used correctly, does not have to be a symptom of a weakened contraceptive effect. Such bleeding and spotting are a common side effect when using hormonal methods of contraception, and especially when we start using a new agent. The body needs time to "adapt" to the hormonal changes associated with the change in the preparation. If the change of pills was carried out correctly, contraceptive protection is preserved.
