Pre-ejaculated fluid (not sperms)rubbed on fingers and wiped off on body for 5 mins and then fingers inserted in her. Could this risk her for pregnancy?

Possibly. Pre-ejaculate may contain large amounts of viable sperm (less common), smaller amounts of sperm that are dead or alive or no sperm. There is potential for pregnancy with pre-ejaculate. Sperm need to be deposited in vagina or at introitus for pregnancy to occur. If any fresh, moist pre-ejculate was on the fingers, then there is potential for pregnancy.
There is sperm. in the" pre-ejaculate",however,very unlikely that the above scenario would result in pregnancy.
