What happens when I take birth control pills and take an extra "pill after" once?

Thank you very much

For @Xxxxxxx: The hormones contained in the tablet may affect the appearance of mucus. In contrast, abdominal pain is a common side effect that occurs after taking a pill after.

Is it normal with the 3rd day after taking the tablet after my stomach hurts and I had gestures of milky mucus, I still take anti tablets

To @Xxxxxxx: This is unlikely to have a significant effect on the occurrence of withdrawal bleeding, although this cannot be completely ruled out. In addition, spotting may occur when taking active tablets.

And can taking this pill after delay bleeding when I start taking white pills?

To @Zadajemy: An excerpt from the article attached below, which answers your question: "If you use hormonal contraception (pill, patch or disc) after taking the "pill after" you can continue to use it. However, it should be remembered that ulipristal acetate (e.g. EllaOne) can reduce the effectiveness of regular hormonal contraceptives and until the start of the next menstrual cycle you can not rely on them and additional protection is necessary." If you take Escapelle, the contraceptive protection of birth control pills is not impaired.

Yes I understand but I'm not sure if I took the pills well or maybe by chance I took something that could weaken them and so for a calmer head I took the pill after and my question whether something interferes with the anti tablets or can ovulation occur if, for example, I took them correctly earlier
