Hi Skymom65,
welcome to this Apple (user-to-user) Community!
Re: "I would like to know why Apple is continuously charging my bank account for things not showing up on my purchase history every single week ?"
We are all Apple users, like yourself, in the community, so no-one here has access to your account or details.
Altough we can not check it out for you, we'd like to help.
Could a family member be making regular purchases, or using a subscription, perhaps ?
See: Get help with charges from apple.com/bill - Apple Support
or
Several purchases might be grouped into one charge.

You may (or may not) have some kind of authorisation set (or needed) for purchases ?

Re: "This has been going on for awhile".
Wondering if the charges are actually from Apple., or whether it is a scam of some kind, using Apple's name.
You might want to compare how the charges appear on your financial provider's statement, with a charge that you know is genuine because it is in your purchase history.
If you think your Apple Account has been compromised - Apple Support : change your Apple Account password
