take a pack of 28 birth control pills every day, but I lost the second pill and couldn't find it. I took the third pill. During this time, I had sex on the day I took the first pill. Pharmacist, can you tell me what to do if I lose the second pill of a pack of 28 birth control pills?

Hi doctor! Doctor let me ask, oral contraceptive pill, if you finish taking the first pack and have sex within 7 days of stopping taking the pill, is there any possibility of pregnancy? I hope the doctor can help me. Thank you.
