I'm a murderer

I think I killed the yeast I pitched into the must. In my impatience I might have not waited until the must was cool enough to put the yeast in and it hit me like 3 hours later. I have to wait a couple days to make sure it hasn't taken hold and then buy more yeast. The must should be fine for a few days, especially if I throw in a couple campden tablets if nothing starts by Sunday.
