When to expect menstruation after discontinuation of Evra contraceptive patches?

Yes, pregnancy can be excluded.

However, if 60 days have passed since intercourse and the tests come out negative, can I exclude pregnancies 100% already?

The potentially infertile time in the case of a 28-day cycle begins around the 17th day of the cycle. However, it should be taken into account that although the chances of getting pregnant during "infertile days" are small, fertilization may occur. Intercourse taken at this time does not provide 100% safety.

I still have a question, is intercourse 7 days before the period with regular cycles safe infertile?

Yes, the test result is reliable. The probability of pregnancy despite the occurrence of two normal menstruation is negligible.

And another little question, whether 50 days after intercourse a negative test is reliable? Can this late period be associated with the withdrawal of patches and not a possible pregnancy? After intercourse there was a period of 2 times in the correct term.

Menstrual disorders even after short-term use of hormonal preparations can take place, and especially if they have been incorrectly discontinued (as in your case).

Menstruation is unlikely to appear earlier than about 28 days after the onset of withdrawal bleeding, but it must be taken into account that after the use of hormonal contraceptives, menstrual disorders may occur (especially soon after withdrawal), which is why menstruation may appear a little later / earlier (although there are cases in which it appears even after a few months).

Is it normal that even after such a short time of using the patches, menstruation also occurs?

Can I assume that this bleeding from the withdrawal of patches was as menstruation and count the next cycle since then? The correct menstruation should be now and it is late so I do not know whether to count from the correct menstruation when the patch was glued or when there was bleeding from withdrawal?
