Is this a seedling sprouting? a.longifolia

Do they always sprout bippinate leaves first? Ive done some searching and havent found any just sprouted photos.
The pic attached is on a spot where I planted an a.longifolia seed so am wandering if this is it sprouting?? Or just a random weed?
I had it in boiled water for some time but still wasnt sure if it was sufficient pre-treatment.

Looks to be a random weed.

Thanks have seen that but thats a month old seedling. But yeah I still think youre right and its just a weed.
