Based on the information you provided, it seems that you changed your Netflix plan on February 2, and your renewal was supposed to be on February 18. In this case, it is likely that your subscription will still auto-renew on February 18, as Netflix usually processes renewals on the same date each month unless you manually cancel the subscription or change the payment settings.
To confirm whether your subscription has been renewed, you can check your Netflix account settings or your email for any notifications regarding the renewal. If you want to ensure that your subscription is renewed correctly, you can also contact Netflix customer support for assistance.
