3rd baby no movement?

Hey I'm a little worrie, I have a 10 yr old and 8 yr olds and cant really remember when I felt their movements. I've had losses after most recent being at 9 weeks last year. I'm 16 weeks and so glad but I thought I would start feeling movement by now? I think I do and then I think I may be imagining it 😔 has anyone else not felt movement at this stage with their 3rd pregnancy being this far? Thanks
