sick and tired of personal questions!!!

So everytime I go to a doctors appointment my mil always has to ask "how much weight have you gained?" ..  and to me this is personal idc if you're family or not and I mean it's a harmless question but, if you really cared about my well being you wouldn't ask personal questions like that because one it's my business and my doctors and two I'm insecure and i would rather not share that information.. and tonight my hubbys grandma asked the same question and I answer "why does everyone has to ask me that?" And then I told her. OK I wasn't trying to be rude but come on that's not an appropriate question and it frankly pisses me off that everyone thinks it's okay to practically invade my personal space. I mean for instance, at my baby shower we were playing the game where they try and guess how big your belly is with a string.. ok well I was wearing a sweater because i was wearing a dress that hugs my body and I have love handles and I just feel insecure without my sweater on and during the game everyone said "take off your sweater so we can see better !" And I respond politely saying "no I'm comfortable with it on" and so we continue the game and everyone comes up to me to wrap around the string to see if they got the right measurement and they were pulling up my sweater ( it was as long as my dress and covered up my butt and it was open and didn't cover up my belly) and they were basically holding it all the way up to where it was showing everything and I even got frustrated and said "stop" but it's like that meant nothing and they kept going. Let me tell you in this moment I felt violated to say the least. I am fed up with people thinking it's OK to touch my belly, ask me personal questions, remove clothing that hides my insecurities, like who the hell are you?!? It's like when you're pregnant you lose all respect for your privacy and personal space. It tottaly sucks!
