Weed?

So far i have only gotten one of my sprouts to come up and survive past the cotyledon stage without getting eaten. This sprouts second leaves look different from pictures i have seen though. They look just like the cotyledons and are rounded and smooth. They have just appeared about two days ago and are still pretty small. My question is, is that what the second leaves should look like early on, or am i growing something different?

the second set of leaves should have ridges on them.
