Advice please I’m so worried 😢

I am 22 weeks pregnant, this is my 4th pregnancy, 2 of which I’ve had anterior placentas and felt my babies move around 20 weeks, this pregnancy I have posterior and I can’t feel a single thing. On my 20 week scan the baby wouldn’t move it took an hour to get measurements but he was stuck in same position, but the sonographer said he got them in the end and let me go, he can move his arms and legs slightly but not his back, I went for a private scan 2 days later just to see if he moved position but he’s still in same place, the man said he wasn’t worried about him not moving as his heart beat was so strong, and if I’m concerned to ring maternity ward so I did, which they told me I shouldn’t be concerned he’s probably just lazy and they can only listen to his heart on a Doppler as I’m only 22 weeks, but his heart beat is fine, it’s him not moving that isn’t, 4th pregnancy I believe I should definitely be feeling something by now even if it’s just flutters, I’m stuck what I can do as no one will help me or take me seriously 😢 hospital have said come in but they will only listen to his heart. I have asked for a re scan and they are refusing as the man didn’t put in notes that he wouldn’t move!
