How High Is The Risk Of Pregnancy After Unprotected Sex Following Masturbation An Hour Earlier?

Hi I masterbated in the shower & cleaned all the sperm off my penis pulled the four skin back & cleaned it all with warm water & shower cream. I had sex with my partner an hour later without a condom but didn t ejaculate inside her & then put a condom on & finished off. Is there a chance of pregnancy from my previous ejaculation?
