Do you find this a tad weird/creepy?

My MIL is SUPER obsessed with my pregnancy... She used to text me every week and tell me how far along I am(like I didn't know) 
Well, now, on fb, she shared my husband's post, my post, AND saved the video to even post it herself.... She's also(without my permission) keeps taking MY sonogram photos and posting them without tagging me or anything...
Am I just over reacting, or is this a bit much?? 
I just feel as if she's stealing MY thunder, like with her doing all this I'm not even excited to post anything about it anymore.....
