enough bs, let's get serious.

So I've seen a lot of girls on here say that they got pregnant even though they're on bc. I know it's possible because of sicknesses age other medications counteracting the pill. 
But enough bull**** here. Anytime any girl asks the question 'can I get pregnant on bc and using a confom' someone always says yes. Really????
If a girl takes her pill every single day, st the exact time and has nothing to counteract it, and then has sex without a condom, can she really get pregnant? Don't comment 'yes' just to scare people because I know that's it's very unlikely thing to happen in all seriousness. 
If a girl is on top of her pill and does it exactly, then really there's no way it could happen.
I'm sick of hearing people on here trying to purposely scare girls.
Of course, accidents happen and sometimes we become forgetful. 
But if you're taking it correctly, then there's no chance.
