White lies about being pregnant

Hey ladies,

I am almost 5 weeks pregnant and im struggling coming up with lies on why im not drinking. I keep using i am having stomach issue and im just trying to eat clean but people keep asking me. I need some suggestions! Like i literally came from a dinner with my girlfriends just now and i said no to splitting wine because of stomach pains and they were joking about me being pregnant. I hate and suck at lying so im hoping there a magical lie that just makes people stop asking follow up questions lol please help!!!
