If I am taking birth control pills and my boyfriend is using a condom, what are the chances that I'll get pregnant?

Short answer: You're in the 99% statistical range...

Long answer:

Estimated pregnancy rates during perfect use of condoms, that is for those who report using the method exactly as it should be used (correctly) and at every act of intercourse (consistently), is 3 percent at 12 months.

The most frequently cited condom effectiveness rate is for typical use, which includes perfect and imperfect use (i.e. not used at every act of intercourse, or used incorrectly). The pregnancy rate during typical use can be much higher (10-14%) than for perfect use, but this is due primarily to inconsistent and incorrect use, not to condom failure. Condom failure – the device breaking or slipping off completely during intercourse – is uncommon.

------------

The typical use of male condoms, which is the average way most people use them, has a failure rate of 14-15%. This means that 14-15 people out of every 100 will become pregnant during the first year of use. Spermicidal agents increase the effectiveness to over 95% when used correctly and consistently.


If pills are taken every day at the same time, and each pack is started on time, oral contraceptives are 99% effective in preventing pregnancy. On average, oral contraceptives are 93-97% effective because women often miss pills or do not start a new pack on time.

Very very small, you seem to be doing all the right things.

.001%

PROBABLY SLIM TO NONE!!!!

like they say, the oral contraceptive is like 99.2% effective......the room for error is for gals who forget to take their pill at the same time every day........always take it at the same time everyday, so that you will remember...i have dated gals on the pill......even without a condom, we never had a problem with pregnancy issues ever.......take care....Brian.....
