Sex question.

Katy • Married to my best friend! After 2 miscarriages we are expecting our rainbow baby. Due Sept 13th 🌈👶
I try to lay down for a bit after my husband finishes inside me. Just to keep Those swimmers insode (lol) but sometimes I have to get up and can't lay down. If I wipe seman out will that decrease my chances of getting preg a lot?
