First pregnancy, 14 weeks no weight gain

Sasha

I’m about 14 weeks, almost 15 weeks and I have not gained any weight. It’s a little concerning because I don’t even look pregnant and anytime I mention I’m pregnant I get judgmental looks from people saying “oh you don’t even look pregnant” and it’s starting to concern me a little. I was not a tiny person before, I’m around 190lbs to begin with. Is this normal and when will I start to “show” my pregnancy? I have my next appointment on the 17th this month. I struggle with morning sickness still but am keeping food down the last two weeks. Any advice?
