25 weeks soon and baby isn't

I'll be 25 weeks on Friday and my baby boy hasn't gone above my belly button . I went to a private ultrasound place and they were like wow he is really low . He's always been low. Could I be doing something wrong or could something be wrong ?  He is literally laying at my pelvic bone still growing but not moving up and I'm worried
