Good afternoon janicefromdanvers,
Welcome to the Apple Support Communities!
I understand your iPad is not charging after you updated your iOS. The resource below provides some troubleshooting steps for this issue. If you are using the USB power adapter and cable that came with your iPad, and are plugged into a wall outlet, the iPad may need to be inspected by an Apple Store Genius or Apple Authorized Service Provider if it will not charge.
If your iPhone, iPad, or iPod touch won‘t charge
Take care.
