What are the chances of twins?

Kayley • 24 years old, I have a little boy who’s 4 and I’m TTC my second baby!! 👶🏻
Anyone have any clue of the chances of twins if :
My dad is a twin
Partners mum is a twin
My auntie and uncle are twins
My grandad's brothers are triplets
Just curious to what the chances are of me having twins in future.
I just had a son who obviously wasn't a twin, but is there higher chance of my next pregnancy being twins👭x
