Expert answer:
The pill contraceptive used failure decreases its effectiveness in preventing pregnancy and, therefore, when not used correctly, the possibility of becoming pregnant increases.
At failures of contraceptive use are usually:
- Forgotten tablet;
- Taking the tablet outside normal working hours;
- Extended pause interval between cartons;
- Take the tablet at a different time each day.
All of these failures can decrease the efficacy of the pill and, consequently, increase the chance of getting pregnant.
When the woman has failed the method, another contraceptive method (eg, a condom) is recommended to ensure she does not become pregnant.
