I NEED ADVICE PLEASE HELP ME!!

I am 31 weeks pregnant and my family do not understand personal boundaries my dad has been touching my stomach 2-3 times a day (everytime he sees me) he touches me everyday and even when I tell him he's not awake, he will shake,pat, and pinch my stomach to try to get him to move. I am extremely uncomfortable with this and it makes me absolutely sick to my stomach. I tried to say it's uncomfortable and he threw a big fit about it. I am at my wits in and the thought of dealing with this for 2 more months makes me want to rage cry! How do you ladies nicely tell your family members that it's your body and just because you're pregnant doesn't give them free rein to touch you anytime they want.
