what is growing in my new lawn

[84dime]

I am wondering what this stuff is and if it's OK to continue trying to grow grass along side it. I'm thinking it is white clover but I really have no idea. Is this stuff going to hurt growing my lawn? Anything I can do about it? Thank you -Josh

Not looking like clover, but a little too soon for me to tell what it is. Bunch of seedlings of something.
