How screwed am I on the scale of 1-10?

Alright guys so I’m travelling from a European country to Ghana in a few days, and one of the requirements is a yellow fever card. Now I was born and spent most of my childhood in Ghana, so I know I’ve had the vaccine but my parents have no clue where records of that would be. I don’t think it’s appropriate to pay privately for another dose just to get a slip but will this cause me issues when I land? Thanks in advance
