people touching the belly

so I needed to vent and see how many of you feel the same way or went through it. I'm almost 13 weeks pregnant and I think I will have a big baby and I'm showing a lot already. I only told my family and my boss. the reason why i told my boss was because I was going to have a lot of doctor appointments. she is super excited and means well. I think my coworkers already think I'm pregnant but are not saying anything. my boss, everytime she freaking gets a chance goes and touches my belly. I knew I wasn't gonna like to be touch even before i got pregnant. I think having a baby does not make it ok to touch someone's belly, if you would normally not do that. I'm getting more annoyed by it every time it happens again. i can't really wear those tshirts that say don't touch yet since I'm still keeping it a secret to the rest of the people. I don't want to be rude and stop her since she is also my boss and we have a good relationship. I figured this would be a good place to vent and hear everyone's experiences or opinions. thanks for reading.
