Is it normal for butt implants to be uncomfortable to sit on?

I am 2 weeks post op from my butt augmentation. I feel good about how I am healing, however, sitting on my implants is like sitting on a large hard bubble. I know there is probably an adjustment period, but it makes me nervous if I'll ever get use to the feeling of them. I am very thin, is there a chance they'll be uncomfortable to sit on forever? Thank you for the feedback!
