I'm so upset..

I really need to hear if I'm overreacting ...from the get go I've been weird about people touching my belly it even took some time for me to get used to my husband doing it. Anyway my husband told his mother on more  then one occasion that it makes me uncomfortable her response to him last time was well to bad that's my grand baby . Later the same day she started rubbing and pushing on me to get the baby to move I backed away saying sorry but that makes me uncomfortable she laughed and said I was crazy. 
Anyway I can't stop thinking about it I feel so dismissed and almost violated by her action then hearing what she had said after the fact made it worse
And no we don't have a good relationship so I def prob take more offense but ... 
Am I totally wrong feeling like this?
