Can a condom fail even though it has no signs of splitting?

No condoms have split but my girlfriend is pregnant, I know I should belive her but is it possible has been cheating?Can a condom fail even though it has no signs of splitting?
sometimes there could be a tiny hole or the condom expired...


and besides condoms are 99.9 percent effective...





so theres just that .01 percent chance...


and yes, some people do beat the odds...





Still, if she insists its urs... do ask her to get a blood test and tell her not to get offended....





ur just....in 'shock'...





and if u want a kid with her now 'Congratulations!'


if u didnt.... erm... ..yeah.Can a condom fail even though it has no signs of splitting?
Yes you can still get her pregnant. Sometimes there can be microscopic tearing that allow sperm to pass through. These tears may not be visible and may not cause a full blow out.





Condoms are not 100% effective. Realistically, they're only about 87% effective. So you could have gotten her pregnant, you shouldn't assume she's cheating.
I am in the Medical Field





NO birth control is 100% effective but abstinence





A small pin hole and even semen on the outside of the condom can get her pregnant..





I would ask for a paternity test
