okay, so my girlfriend is on the pill, and i use condoms when we have sex. what are the chances that she gets pregnant? i mean, we have done it a couple of times without the condom, but i always pulled out before i ejaculated. if you guys can help, that would be great.

if she's taking the pill properly, the chances of her getting pregnant are slim to none

well then, there are days where she has forgotten to take the pill, and then took two the next day. is that a good thing or bad?

well that's not recommended. she should take it consistantly, every day at the same time. if she misses you should use a condom, just for backup to be sure

Just so you know, it's the girls who keep forgetting to take it and double up on doses once they remember that often get pregnant while on the pill. If she was taking it the way she was supposed to, at the same time every day, then it wouldn't really be an issue. But since she can't seem to take it correctly, then you may seriously be exposing her to risk of pregnancy if you're not willing to use a condom.

You have to ask yourself what's more important: sex without a condom but with an increased risk of getting her pregnant? Or sex with a condom knowing that at least you're partially protected, even if she can't take the pill correctly. The choice is yours.
