Is there a chance of pregnant after having a one night stand?

Yes it is possible. I have gotten a someone pregnant from a one night stand. But if you do have one night stands you should always use protection. I am the one that always uses protection and the one time i didn't use it i got someone pregnant. You might think of it as a mistake as so many do, but it would be the biggest mistake you will never regret. The kid will be the most amazing thing of your life. It will frustrating and confusing at times as no person is ready to have a kid but everyone will make it through it as long as they keep trying and loving.
