Updared Credit Card

I got a message that my card couldn't be processed. When I look at my account it says that it was processed and the payment was received but I did change credit cards recently. I changed the credit card without issue but I am worried because it has been almost 30 days (the message came to my spam folder and I just found it) I rely on the domain for my shop. Since it is updated now I am assuming it will be okay but I am wondering why it said the payment was processed fine.
