Hello, I started taking the antibiotic (Klabax) on the 4th day (21.10) during the 7-day break, I will stop taking it on the 4th day of applying the evra patch (28.10). Will the pregnancy protection be maintained 7 days later??? Can ovulation occur? Will hormonal contraception (evra patches) be weakened for the whole month? I'm also worried that today, on the 2nd day of applying the patch (25.10) I still have withdrawal bleeding, even though I've had the patch on since yesterday morning. Please reply quickly.

To @Klaudia:
Milk leakage can indicate a hormonal disorder, such as elevated prolactin levels, which can occur after the use of certain medications, although antibiotics rarely cause it. However, if there is a leak, it is worth doing a prolactin test, as you plan, to rule out possible disorders. In most cases, antibiotics do not affect the effect of contraceptive patches because they do not interfere with the absorption of hormones through the skin, but it is always worth discussing worrying symptoms with your doctor.
If I have a milky discharge from the effects after taking an antibiotic, can it interfere with the patches? I will be testing prolactin soon, but I have never had such a situation before

The risk of the use of the antibiotic Klabax weakening contraceptive protection (and thus ovulation) is very small. You can read more about it in our article (paragraph "Antibiotics"): https://www.gdziepolek.pl/artykuly/jakie-leki-oslabiaja-skutecznosc-antykoncepcji
As a precaution, additional protection can be used during antibiotic therapy and for 7 days after its completion. After this time, there is no reason to worry about the effectiveness of contraception.
Withdrawal bleeding may last longer and after the first patch in the cycle is applied. This should not be a cause for concern. The length of bleeding may vary from cycle to cycle. The length of bleeding can be affected by factors such as excessive stress or illness.
