(probably thriller) with blonde woman and a baby, i have screenshots

So there was a trailer on a tv channel but there was no audio from the movie just some creepy sound plus there was (obviously) no name of the movie and idk why. Plus there is a scene where woman sees various pictures of herself on some wall, probably stalker’s wall.
here are the pictures, i think thats charlize theron and sean penn maybe but i dont think so…

A Mother’s Instinct / Her Own Justice (2015)?

Isn’t this the same pendant as on the guy on screenshot 3?

Laura Harris plays a short-haired blonde, like on screenshot 4 and Kim Coates as the guy that looks like Sean Penn.
