Can anyone explain this? The midwife didn’t answer none of my questions😐

So I had my 32 week growth scan yesterday (due to my health i have these 28, 32, 36 weeks).. after tech did measurements etc she looked concerned looked at my previous measurements and said she wants to do the measurements one more time as the baby isn’t getting bigger and measurements are dropping below my 28 week ones and not following the line now. I have been saying for the last week I feel like my bump isn’t getting bigger but I feel smaller🤷🏼‍♀️ anyway they’ve told me I need to go back in 2 weeks to check if he’s growing again. I asked Midwife is it’s something I should be worried about but I didn’t really get anything back or any information to ease my mind 😟 I’m a ftm and I’m worrying now.

Has anybody else experienced this? Should I be concerned now I’m feeling like he’s coming early!🙁
