Not sure this is the right place to ask but I'm desperate.
A few days ago I had a one night stand. After we had sex I went to take my condom off and noticed it must have come off on it's own and it was empty.
Now I'm scarred she might be pregnant, so I've been trying to find out what are the odds she'll get pregnant after one time but I've not been able to find a proper answer.
Also she is 39 so that should decrease the likelihood right?
Any help would be greatly appreciated.
