No. Once the book has been issued to your account the due date will not change.
The only time a loan period of a book will change is if you find a resource on the shelf and it is reserved by another user before you try to borrow it; the loan period will automatically reduce to seven days before you issue the book. This is to ensure the fair circulation of resources. Check your self-issue receipt for the due date rather than relying on the label on the spine. Keep track of your loans online by logging into your library account.
