I put on the third Patch Evra on Friday, after two days I have to remove it, that is, on Sunday, then the fourth patch I have to glue also on Sunday?

If you glued the third Evra patch on Friday, you peel it off only after 7 (not 2) days, i.e. in a week on Friday at the same time. After peeling off the third patch, you need to take a 7-day break for withdrawal bleeding - do not glue the fourth patch.

To @Justyna:

You did the right thing. Further treatment depends on how long the patch has been removed (even partially). According to the manufacturer's information, if the patch was removed:

- for less than one day (up to 24 hours): immediately reapply the patch in the same place or put on a new patch, but you do not need to use an additional method of contraception. The next Evra patch is applied on a fixed "Patch Change Day";

- for more than one day (24 hours or more) or if you do not notice when the patch has come off: there is a risk of reduced contraceptive effectiveness, stop your current cycle of contraceptive use and start a new cycle of use immediately with a new Evra patch. A new "Day 1" and a new "Patch Change Day" are established, and you should not forget to use a non-hormonal method of contraception (e.g. a condom) at the same time during the first 7 days of the new cycle.

If the patch adhered completely to the skin before removing and you immediately applied a new patch for 24 hours, the next one should be applied on the agreed "Patch Change Day". If the patch peels off again, consider changing where you apply it.

This is the first time I have used evra patches. 1 patch on Friday, the 1st day of the cycle, fell off on Tuesday. And on Tuesday I immediately put on a new one. Did I do the right thing and when should I wear another one?

Thank you for your help🤗

Bleeding may or may not occur. In the next cycle, spotting or intracyclic bleeding may occur.

And, can bleeding occur? Is it only after a new cycle of patches

To @Maciej: Start a new application cycle immediately with a new Evra patch. The day you put on the patch will be the new "Day 1" and the new "Change of Patch Day". It is recommended that you use an additional method of contraception (e.g. a condom) at the same time during the first 7 days of a new cycle.

And how was it taken off yesterday (Tuesday)?

To @Maciej: You can put on another (spare) patch on Tuesday and wear it until Thursday. Then take a 7-day break.

And if the wife did not remove the patch on Thursday, but wore it until the next Tuesday, how next?

To @Maciej: In this case, peel off the patch on Tuesday on Thursday and put on another patch from the spare pack on Thursday. In this case, the "Change Date" remains unchanged.

Mrs. Catherine's wife changes the patches on Thursday. Peeled off 2 patch in the back. She took it off and glued it on 3 on Tuesday. Is he supposed to take it off on Tuesday, take 7 days off and wear a new one the following Tuesday? This is how the day of change will change and will it be OK? No additional concept method needed during this time?

Yes.

The third patch of Evera I put on on Friday is on Friday I have to take it off and in a week on Friday start a new packaging?

If you have to remove the current patch on Sunday and glue the next one, you should do it immediately after removing the current one on Sunday.
