Adobe Creative Cloud Subscription Cancelled Without My Warning?

On Wednesday, November 14th, I purchased an Adobe Creative Cloud Photography 20 GB Plan for the first time. I did a month-to-month subscription plan, and according to my Bank statement, I've been charged the $10 for my first month. I've been using it for a few days no problem, but this morning I got an email that my payment is past due and that my membership has been expired and not renewed. This doesn't make sense to me - I paid for it just a few days ago and have been using it just fine until this morning. When I log onto my Adobe account, it tells me I need to input my payment information for my plan again. I'm afraid that if I do this, it will try to charge me yet again for this month of my plan and I can't afford that. Also, on my bank statement, it says that my payment for this plan is still processing, and I don't know entirely if that is affecting any of this (also don't know why it's still processing - it's been four business days since I purchased the plan).

I know this is a lot, but believe me, I'm confused too. Anyone have any advice/anything I can do to fix this?
