wordpress login secure but url isn’t

Any help is appreciated. Thanks in advance. My wordpress url is secure. https://plumberswichitaks.com/wp-login.php but my actual site is not https://plumberswichitaks.com/ Well that is crazy! When I copy the url from my browser it shows it is secure. But when I am actually looking at the site in my browser it says “not secure”.I am using chrome but also tried it in microsoft edge. Anybody have any thoughts? Again thanks
