Work harassment ?

Morgan

Okay so this has been an issue since august (a month before I got pregnant) but I work in an office & everything is pretty calm everyone gets along but ever since I moved to this department about a year ago this older women (like 65) has taken a special interest in me. She loves to be in everyone’s business but especially mine. I can’t list all the examples or I would be typing all day but she has been progressively got more and more invasive & for lack of a better term creepy since I’ve got pregnant. She’s always been in my business but when I announced my pregnancy she started getting creepier.. she took my sonogram picture when I was announcing & I nicely said “oh I’ll take that back” & she refused to give it back & hung it up in her cube.. she also references my baby as OUR baby when talking about it.. she keeps trying to get information about my baby shower I’m planning & texts me on weekends when we are off. She even called a coworker that I’m friends with the other night & asked her if she knows the gender of my baby & my coworker knows she’s weird & so she said she didn’t know & so she continues to ask if ANYONE else knows that she can ask or who I told All things going unanswered & I’ve explained to her before the baby that I want to keep my business to myself & barely acknowledge her at work bc I’m just so uncomfortable around her.. I’ve asked my supervisors MULTIPLE times to move me away from her bc she makes me uncomfortable.. & they’ve made it into a joke kinda. I should have to deal with this added stress while pregnant right? What can I do to make them take me seriously...?
