And does the use of such anti-reducing drugs, such as an antibiotic or a large dose of paracetamol, have to be counted simply from the day of taking it and the previous intercourse is secured on the patch? Does this have any impact on the fact that previous relationships may be left unsecured?
I'm asking because I'm quite sickly and I often take antibiotics, can I understand it in such a way that when intercourse took place on the 2nd patch and I started taking an antibiotic on the 3rd patch or stronger drugs, the previous intercourse was secured and the medication decreased only from the day I started taking the medication? Because I understood it to mean that contraception is not retroactive

Colds or cold medications do not affect the effectiveness of the patches.

Changing the day on which bleeding occurs should not be alarming. The colour of the discharge also has no effect on the contraceptive effect of the patches.

You can read about which drugs can weaken the effectiveness of the patches here:

And could the use of medication to reduce the patch during a break when I don't have it also affect the fact that my period was late? Do these medications actually lower anything when I don't have the plaster on anymore?

And as I asked, do such immunosuppressive drugs, or drugs simply during the course of the disease, have an effect on previous intercourse, or can they reduce the effect of the patch only from the day I actually started taking it, and the previous intercourse is secured?

Thank you very much for your reply, I always change the slices regularly on "patch change days". I've never forgotten to take it off or change it, I'm very careful about it.
Yesterday, 4 days after removing the patch, I got dark brown spots, but today it's blood, but also very dark, looking black sometimes. But I'm guessing it might just be due to medication, illness and a lot of stress in life. My general day when I get my "period" are Tuesdays, which is 4 days after removing the patch, but will I have such days that my period will come on Wednesday is it okay too? Nowhere does it say how many days exactly the bleeding should come, only that it should just be during the break I wanted to ask more, for two years, as well as before contraception, I had very painful periods, my last withdrawal bleeding was practically painless, I did both ultrasound and cytology right after it was finished, but everything came out normal. This bleeding is also painless. Is it a symptom to anxiety that I suddenly have a painless period? I know that, in theory, your period shouldn't hurt. Should I protect myself from this new cycle? I put the slice on Friday.

To @Gosia:

Everything indicates that you have been protected and you are protected now.
It is important that you do not wear one patch for more than 7 days and that the interval between successive packets of patches does not last more than 7 days. The cold medications you mention do not affect the effectiveness of hormonal contraception.

On the other hand, the lack of bleeding on time may be related to the ongoing infection and weakness of the body.

Hello, I've been on Evra patches for about two years, on Thursday (3rd patch) I was undressed by illness and started taking cold medicine, Tabcin, Acti-trin syrup, Iburom Max, and the allergy drug Rupurix. On Wednesday I had my last intercourse (I additionally protected myself with a condom), from Thursday as I mentioned I started taking cold medication, on Friday I was out of date to remove the plaster. My question, because I know that the use of medication for a few days could reduce the effectiveness of contraception, and I have been using it since Thursday (today is Tuesday), whether the intercourse I had before I started taking the medication was protected because I did not protect myself at that time, but on my logic, contraception does not work retroactively and the intercourse I had after taking the medication counts. Did I do the right thing by following the calendar and removing the patch, or should I skip the break and start using the new packaging? And does the use of drugs currently without a patch affect the effectiveness of applying a new one? Can the use of cold medication for a week (sticking to the doses because I did not exceed the dose of 3 g of paracetamol) reduce the effect of the patch? I'm running late withdrawal bleeding
