I would like to get advice about daily birth control pills. Since this is my first time using them, I don't understand them very well. I just finished my period 2 days ago (1/5) and on the 3rd day (4/5). Doctor, can I take the first pill of the daily birth control pill 2 days after my period ends? From the day I took the first pill plus 7 more days, can I have unprotected sex? Thank you, doctor.

Normally, I take my birth control pills every day at 8:30. Now, I want to change the time to 7:00 for the new pack. Doctor, can I change the time I take my birth control pills every day? I take a pack of 28 pills.
