Way too early to tell, especially if you don't have a lot of experience. Some folks can tell at this stage with really powerful candling equipment and a very dark room, but even then you really need to know what you're looking at.
Try again in two more days--you *may* be able to see something at that stage, but I wouldn't even think about tossing anything until at least 7 days when you should begin to see clear signs, even to an inexperienced eye.
Good luck!!
