I am on my 21 day contraceptive pill. This is the first month that I am taking pills. Today is the 26th day ie. 22/05/2024 (hormone free day, no pill taken). I can feel slight blood spotting, so I am not sure if my periods have actually started or not. But I had unprotected sexual inter course on 25th day of my cycle at night ie. on 21/05/2024. Do I need to take emergency pill within 72 hours or will the contraceptive pill do its job of preventing pregnancy.
