Sounds like you have BV and the Gonner. But this would not prevent you from spawning.
A yeast infection most likely wouldn't stop you conceiving.
But are you sure this IS a yeast infection? It sounds more like some other kind of vaginal infection (not necessarily sexually-transmitted) A yeast infection doesn't usually cause yellowish discharge, and "foul" smell.
I would go and have this checked out, because some pelvic infections CAN hinder conception.
