An order status of "
order processing" means your payment was received and confirmed.
As long as you used the real website (linked the "code" box below) and your order status confirms they received the payment, you do not have anything to worry about.
I only mention the site because the status you stated is not exactly a phrase I am familiar with this source using for an order status -- and, there are many fake/scam sites that pretend to be this source.
But if you know you used the real site and the order is listed there as "order processing," it means there is no confusion about where the payment went; the source updates the status from "awaiting payment" to "order processing" when they confirm the payment was received.
After that, it is just a matter of waiting for warehouse workers to pack and ship the order. In my experience W3 orders ship a week, or sometimes even faster (I have had some one ship just one day after status update), than the time the payment was confirmed.
But, like with any business, it just depends upon things such as if workers took off work or understaffed, or just lazy, or someone may quit/fired etc. and disrupt typical efficiency.
As long as you have that order status though, you will be alright because the source is stating they have the payment and are processing the order.
