I am 5 weeks post op BL & BA. Is it normal to feel the implants moving around when I bend and do activity?

My surgery was on 6/22/16. I slept on my sides about 3 days ago and woke up feeling pain in both breast as well as movement of both implants. I'm also feeling a gurgling/vibrating type of sensation anytime I move/bend over. My left breast still has not dropped and both feel very tight. I'm currently wearing a cami/no bra and taking Valium at night to relieve back and chest spasms. Are these symptoms and sensations normal at this stage? I am 5wks post op. Right breast has the most pain.
