Dry Sperm and wet wipe pregnancy risk? PLEASE READ ALL?

My girlfriend went away from home recently and before she came home I masturbated and a decent amount of sperm accidently went into my boxers. I went to have a shower and saw the sperm which was dry and got a moist baby wipe to rub it all off. Once i got all the dry sperm off I left the wipe on the side. The problem is my girlfriend picked it up and but it in the bin without me realising. about 5 minutes later we were having sex and she rubbed her vagina with her hands Is there a chance she could get pregnant? could the sperm have survived in the baby wipe and contaminated her hand? The sperm was on the wet wipe for about 10 minutes before she held it.
