A pending charge may mean you have something such as a subscription trial that transitioned to a paid subscription but there was no method available in your account to pay for it. This support article about how apps, content, and subscriptions from Apple are billed https://support.apple.com/118244 says:
“If none of your payment methods can be charged, your account shows a negative balance. You can't buy, download, or update more apps or items until you update your payment method. ”
