Is it okay to take birth control pills every day at the wrong time?

Question
Hello doctor,
Currently, I have started taking birth control pills daily for 4 days of my menstrual cycle. But the first 3 days, I did not take the medicine on time, each pill I took about 2-3 hours late every day. So the doctor asked me to take the birth control pill every day at the wrong time? I can still take the medicine as usual and at the right time, the medicine will still work, right? Or do I need to use other birth control methods until I start using the new pack, doctor? Thank you doctor.

Hello,
With the question “Is it okay to take birth control pills every day not on time? ", the doctor would like to answer as follows:
Daily oral contraceptives usually contain estrogen and progesterone (these are two female sex hormones), which have the effect of preventing ovulation, thickening the cervical mucous membrane, preventing ovulation. Prevents sperm from swimming towards the uterus to fertilize, changing the uterine wall not suitable for egg implantation, thus preventing pregnancy. Currently on the market there are many products for daily contraception, divided into two types: blisters of 21 pills and blisters of 28 pills.
If you forget to take the pill for more than 12 hours, the contraceptive effect will be reduced. If you don't take your birth control pill on time, you can still take it as usual and remember to take it at the scheduled time.
If you still have questions about taking birth control pills every day on time, you can go to a hospital under Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
