My mother is driving me crazy

My mother is driving me crazy. She doesn’t want me posting pictures of my ultrasounds on Instagram because “the weirdos will see it” I have no clue what she means when she saw the post she liked it but also felt the need to comment “wait in silence”. Like I really don’t understand her reasoning for all of this my daughters father is blocked on all social media so he’s not seeing pictures of her any time soon as well as his mother. Like I feel like I haven’t been able to enjoy my pregnancy which is upsetting because it’s going to be over literally any day now and it’s because of things like this that I feel that way and she doesn’t seen to understand she’s making me feel like my pregnancy as well as my daughter is something that needs to be hidden.
