my parsnips didn't germinate

I planted tender and true and they came up in about two weeks, I didn't do anything fancy cos I didn't know they were hard to germinate.
Trouble is I don't know if they are still there, as I can't distinguish between them and weeds as I don't know what they should look like after the second leaves come through

What they look like has been brought up before, but darned if I can find it. Anyway, this is what they should look like...
