Husband's ex.

This doesn't really belong anywhere but I'm needing this advice. My husband and I have been together for 2 years, married one. His girlfriend before me has just been so so bitter about everything. I worked with her and she was constantly saying awful things about me behind my back even though I'd never personally talked to her. After she finally quit, she blocked me and my husband on every form of social media. But people have showed me posts she's been making over time. When we got started dating, got engaged, married, and now pregnant she made some post about it. I thought it was kind of annoying, especially since she has us blocked on everything that she was getting all this info and trash talking it. But I ignored it. Now Instagram has its new story feature, kind of like snapchat. I was looking at who viewed it last night and even though she has me blocked she's been viewing my stories! This has been dragging out, it's annoying and sad. Should I say something? Should I not? Two years. And she has even dated other people.
