I am 5 wks post op BL and Aug. Is it normal to feel the implants move around and feel an odd sensation?

My sx was on 6/22/16. I'm 5 weeks post op. I slept on my side about 3 nights ago and woke up with pain in both my breasts. Since then I feel the Implants move every time I press my arms together or bend over. I also feel an odd vibrating/gurgling sensation when they move. Is this normal? Left breast still has not dropped. And both still feel very tight and high. Currently still wearing cami no bra. Still on Valium at night for spasms in back and chest.
