So I'm 3 months pregnant, Not showing sometimes really bloated but I'm not showing. People keep trying to rub

my belly and pull my shirt up. Well, I'm not fat but I'm bloated and I look kinda pudgy around my belly and I don't want people touching me thinking I'm all squishy and fat when its just bloating and I'm not showing its too early. What can I tell people? Has anyone had this problem? When I have a belly I will love to have people touch it (I better b/c I made my sis-in-law sit for 30 min while I poked at her belly once)
