What are the chances of pregnancy if...?

Wow, someone's slightly paranoid. XD

0.000000000000000000000000000001. And that's if the condom doesn't break!

I would say.zero.

id say ZERO unless you ave some kinds freak-accident
but I understand why ur worried, I had sex with my ex plenty of times, with no pill, condom, and I didn't always manage 2 pull out,
she told me she was pregnant once and I spent 2 hours staring at the wall in my kitchen, the cheeky thing was she told me by text, I probably would of handled it better if she said it 2 my face,
(THIS IS NOT THE REASON WHY I AM NO LONGER WITH HER, ONLY I DICKHEAD DITCHES A PREGNANT GIRL)

Lopok the bottom line is if you are that worried about getting her pregnant and getting her pregnant would be as bad as you are saying then you are not ready to be having sex. Think about it be responsible you are putting your pleasure before the possibility of a child, just think if you did get her pregnant. Could you raise the child? How fair would it be to the child? All for what 2 minutes owrht of fun? Not very good! If you are not ready to raise a child you are not ready to have sex because not matter what you do nothing is 100% effective and you always run the possibility of getting a girl pregnant.
