I have been fooling around with my boyfriend 8 days after my period. He ejaculated on his hands and washed them immediately. A half an hour later, he touched me.
Is there any chance of pregnancy?

By what you describe, no. However, if there could have been any contact of semen either from his penis or his hand to your vagina before his washing his hands, its possible. Depends on what fooling around you were doing.

Be very careful with fooling around as it can be easy for things to go further than you may plan. You have control over just how intimate, and risky, a situation may become.

If he washed his hands and it was a long time after, no there is no chance. But fooling around, will lead to it, if you do not use safety.

Define fooling around and if it involved any penile insertion then you could be pregnant as some men have ejaculations before they pull out for a final one.
