How Long Does Ameren Give you before shutting off power?

I have googled this eight different ways and can not find an answer so I’m hoping yall can help me. I moved in to a new place and my bill is almost a hundred dollars more than I expected - it’s just me, I keep lights off, etc. I try my best to pay on time but this is also my check to pay rent, so I’m a little short. Anyway- The bill is due this Friday. I get paid next Friday. I can try to get it by Friday but I’m worried I won’t have enough. I know about late fees but I can’t find anything about shut offs. Do you think they will shut off my power if I pay a week late? Thank you all in advance.

Editing to say - WOW you guys rock! I love this city! I was expecting maybe two or three replies by the end of the day, but by the time I got to work there were so many helpful comments and wonderful people here. I’ll do my best to respond individually when I have a moment from work a little later :) Thank you all so much, who needs Google? And I know I sounded a little naive here, I totally accept that. I’m usually on top of my bills. My mom wasn’t the best parent and let her bills slide all the time. We had everything turned off often, and all I could hear in my head this morning was her talking about how expensive it is to turn back on. Thank you all for soothing my anxiety <3
