Apparently she started crying after one night stand? What do I do?

Had a one night stand last week, and when she went to the bathroom i left.

Today i bumped into one of her housemates who told me she started crying after I'd left.

should i contact her to ask about it?

Right quick update, I'd met her that same night (she's a friend of a friend).

I should've said bye but i didn't realise it would cause that much upset!!!
