Using condoms and hormonal BC has less than a 1% chance of pregnancy. PCOS could make the chance even lower.
If you have been on birth control for over a month then you are protected against pregnancy.
The same as anyone else's. If you do not wish to become pregnant always use a condom and/or a reliable form of birth control.
It is always possible when having sex - the chances of getting pregnant with the two types of BC you are using together is very, very tiny.
There's a 25-75 chance favoring that you would not get her pregnant. You could use a condom and not get her pregnant, or you don't use a condom and you have a chance at getting her pregnant.
you technically can but the chances are negligible If your using birth control you chances of getting pregnant are statistically 0.1%. using a condom properly 98.1% protection considering a 50% pregnancy rate from unprotected sex means a 0.8% chance of getting pregnant Meaning using both you have a .0008% chance of getting pregnant or 1/1250000 This is a rough statistic and includes the chances of condoms breaking. If your using both it is very unlikely to become pregnant, however sex always carries that risk no matter how careful you are. Its part of the reason why over 100,000 people a day have an abortion.
the probability is very small
after the mences. day betwen 14 to 19.............
The only "birth control" that works 100 percent is Abstinence. But a condom will help prevent it, without a condom you have a low percent of not getting pregnant.
It depends if the boy can ejaculate and the girl has started her started periods.
