I have been on the same birth control pill for over a year now. This month around the 7 th of my cycleba condom broke. I have been taking my pill every day at the same time. What are the chances that I might be pregnant?

Chance is very less. Regular use of oral pill- chance of pregnancy is less than 1percent
If you have calculated 7th day of cycle by taking day 1 as the start of bleeding then it falls in the safe period and theoretically you should not be getting pregnant. Added guarantee if you have regular periods
