How to hide pregnancy? Help..

I’m 14 weeks pregnant and only fiancé and I know about it. Going to visit his family on thanksgiving and I don’t want them to know yet that I’m pregnant again. They’ve been telling us not to have another baby yet because our son is only 2 1/2 yrs old and it’s a lot of work. We’ve been telling them that we do know it’s a lot of work and that we will wait but here we are pregnant again. My fiancé and I are happy about the pregnancy especially that it’s a girl, but I feel like we disappointed them and I’m scared to tell them if they suspect that we’re pregnant again. How do I hide it from them? I never lost my belly pooch after my first pregnancy so now everytime after I eat I look like I’m 8 months pregnant so it’s kinda hard to hide my stomach even whem I’m wearing baggy shirts/sweaters. I know they will also offer me alcohol and if I decline they will ask why. Any advice ladies? I want to hid it as long as I can. TIA!
