Blog Page 2 not showing

I’ve been regularly publishing blog posts, and have 7 in total. But today I noticed my blog page is displaying 6 blog posts but not giving readers the option to click onto page 2 to view the other blog post. Every new blog post I post pushes the oldest blog post off the main and only blog page.

Does anyone have any insight or advice on how I can include pagination in my blog?

Thanks in advance!
