If you forget to take a birth control pill, you should take the missed pill as soon as you remember and then continue taking the rest of the pills at your usual time. If you usually take your pills at night, you should take the missed pill now and another pill at your regular time in the evening. It's important to continue taking your pills as usual to maintain their effectiveness. However, if you forget more than one pill, it's best to seek advice from a pharmacist to determine the best course of action. Remember to always follow the instructions provided with your medication and reach out to a healthcare professional if you have any concerns.
