If I finished taking birth control pills on Wednesday, when should I start a new pack?

To @Ania:

After stopping the contraceptive pill, especially if you experience spotting, it is recommended that you start a new pack on the day you would normally start a new pack. I also encourage you to consult your doctor to discuss the situation and make sure that continuing to use the pills is appropriate for you.

If you have doubts about this situation, it is always worth consulting a doctor who can provide more personalized advice. If you are not able to make a face-to-face visit, I attach a link to the online teleconsultation:
