I have been on daily birth control pill on crisanta for past 3 years. I take it daily at the same time without fail. Last month I continued taking pills without taking any break. I had intercourse on 21st. For extra protection I took unwanted 72. After 3 days the condom broke, so I took unwanted 72 again. After 5 days the condom broke, so I took unwanted 72. meanwhile, I was taking pills regularly. In my pill break, my periods came as usual on the 5th day of my break. But it is very less. It continues for at least 5 days. But it ended on 3rd morning. Is there any chance of pregnancy? Should I take a beta hcg test?
