I agree its too early to yet yet. If you have others growing leave a few to grow so it will be easier to identify.
Over at Scotts Lawn Service we have a great weed identification tool called the Lawnopedia with pictures and other identifying factors as well. In addition if its a harmful weed or a weed you just dont like it also gives useful control methods.
Message me if you have any other questions
