Why Are My Butt Implants Flat?

Hi, I just got butt implants and liposuction on my abdomen 6 days ago, I am suppose to wear the garment for another 3 weeks as one week has passed, But my butt is so flat! Will my butt just pop out one I take off the garment? My doctor put 410 cc implants for me. When I look at myself in the mirror it looks the same size as before but just firmer, everyone tells me it's because of this tight garment but I'm really worried, I hope this is not the final result. Is 410 cc a big size? Thanks alot
