Stomach measuring small

Hi everyone! I went to the regular ob on Thursday and the ob said my stomach was measuring around 29 weeks, but I was 32 weeks at the time. She said they would usually be concerned but since I’m high risk I’ve been seeing the specialist every other week and at 30 w 6 days baby was measuring 3 lbs and 9 oz, which was normal. All this weekend at family events people kept saying how small my bump was and how I looked like I was in my first trimester and it made me feel indifferent and weird. Has anyone else dealt with a small bump? This is our first baby, I weighed around 120lbs before getting pregnant and now I’m 145lbs, I’m also 5’1 so that doesn’t help lol. I’ve included a picture of my belly for reference and I’m currently 33 weeks today. Baby’s been super active and healthy my entire pregnancy and it just concerned me a bit when my stomach measured so small 😕

Update: Thank you everyone for your helpful responses. I feel more relieved and less worried. 💜
