What should I do if I accidentally took the contraceptive pill in the morning instead of in the evening?

You have not given what contraceptive pills you are taking, so I can only give general information. Considering that you took the tablet about 12 hours earlier, you may not take another tablet today, but only the next day. In this way, the cycle will remain unchanged. For your own psychological comfort, you can use an additional form of contraception for the next few days. For most birth control pills, a delay in taking the pill for up to 12 hours does not affect the effectiveness of contraception.
