Tummy looks small when will I show ?

Heather
I'm 15 weeks 6 days, feel like my stomach is flat. Sometimes it's bloated and I look pregnant and sometimes it's flat. Last ultra sound nurse told me to drink more water. I've been trying but it's been hard for me. I'm hoping our lil one is growing and everything is fine 🙏🏽❤ God Bless all you pregnant women and women trying to conceive 🌈❤️💛💚💙💜 🤰🏻👶🏽
