Feel stupid for called maternity ward

Just have to get it off my chest. I had a MMC last year so this is the furthest I have got with a pregnancy first time mum - I’m currently 24+3 and been getting sharp constant pain on my right side of my stomach which last for about 10 minutes if I continue to stand 5 minutes if I sit down. Last night I didn’t really feel baby move and he usually moves a lot between 6pm and 10pm so I rang the MAU and they made me an appointment for today, even though they think the pain is a trapped nerve, now I feel silly and like I’m wasting their time because if it is someone that actually needed an appointment could have had it.. but then again today I haven’t really felt any movement so thinking it’s best to get checked instead of just worrying?
