Please read and answer thank you?

Hello, I feel uncomfortable to sleep on my tummy, It feels 'odd', I'm tierd really early in the evening, and getting cramping legs easily. I suffer frm gall stones, but the pain disappeared, I've been starting to get pain in the back of my ribs mainly to the left, but can be both. I'm have the implant in and have irregular periods, any thoughts, much appreciated tia xx.
