Hi Julie ... there's a bit of a glitch on the forum at the moment, otherwise you could post a photo for us. Hopefully it'll be fixed on Monday.
In the meantime my first thoughts are that it could either be
Mind-your-own-business also known as Baby's Tears .... Soleirolia soleirolii (syn. Helxine soleirolii) a creeping perennial with tiny rounded leaves.
Google both of those and see what you think.
