Convinced baby not growing

[Fairy45]

Sorry in advance for the crazy post. I've been really unwell with an infection that ended up needing IV antibiotics and a few days in hospital, came home yesterday. Nothing related to pregnancy but might be relevant given all the pain relief and abx I've had pumped through my blood.
I'm 29 weeks and at my 28 appointment (11 days ago) I was maybe a bit unwell but not at the stage of hospital admission yet. My bump was measured and plotted as just above 10th centile. I'm already under consultant so already have a growth scan booked for end of next week. Since being in hospital I feel like movements have changed, feeling weaker but still there. But I also feel like my bump hasn't changed size. I'm getting braxton hicks now and can feel that the top of my uterus is just above my belly button exactly where it has been for about 4 weeks now. Is this worth a call or do you think I should just wait it out until the 30 week apt?
Am I just being an anxious Annie?!

If your movements have changed you 100% need to call for advice. They would rather you call 100 times and be fine than 1 time and it not be ok.

I'm sure it's fine. But please check.

My bump measured small every appointment. Never got any bigger than 28Cm. My boy was born a healthy 7lb 4 at 40-+2

I would call based on the reduced movements. I'm not sure you'd notice the size to be honest - I had two normal size babies and one low birth weight and I couldn't tell my bump was smaller although the midwife picked it up by measuring.
