Can y'all share belly pics at between 15-20 weeks? I'd love to wait that long.

Realistically, how long do you think we can wait before telling people? Even close relatives. I want to keep the news just between me and my husband for as long as I can. I'm hoping with it being winter it's a little easier, and I want to wait a long time because I am anxious about the first trimester, I've had two miscarriages but they've been at week 5 and week 8. I'm 4 weeks today. I'm a thick girl (212, 5' 4") so I'm hoping with a really healthy diet and my constant nauseous I gain belly weight and lose a little fat so I have more time.
