Could i still get pregnant even if i use birth control?

Yes,depends on which: No birth control method is 100% even with perfect use (no missed or late pills), the failure rate is 0.3% (less than 1 couple/100 will get pregnant in the first year of use) or 9%-9/100 will get pregnant with typical use of birth control pills. The most effective birth control are iuds or implants. They've also very easy to use, and as effective as permanent sterilization but reversible.
