Help hiding pregnancy!

So I just found out I’m pregnant, the only thing is, I’m 4w, and I told about 6 people I MIGHT be pregnant and now I actually am and I don’t want to tell them I actually am for a while lol so any tips on how you hid your pregnancy and how you hid your bumps and everything would be greatly appreciated!! My cousin also wants me and my man to drink with him this Saturday and I don’t know what to tell him! I don’t plan on announcing my pregnancy for A WHILE, like at least 12-18 weeks along! Thank you!
