How soon will I show?

Bre
Hi ladies,
I'm tiny. Like 5'3, 104 lbs. I am 4 weeks 3 days (per the start of my last af). Right now my hubby says I look like a tiny itty bitty bump or that I am really full from eating lol. Any advise on when I will start to show? I'm assuming since I'm tiny it may be earlier than expected lol
