Ok so I'm eating like crazy, always tired and tossing and turning at night.. 
But I have these times where it feels like my tummy feels bloated and I have light light period pain going from hip to hip and around my back.. It's comes and goes..Just want to know if it's normal?? I have an ultra sound in 9 days 😊😊😊 this is my first baby and I did a lot of excersising befor I feel pregnant because I lost 55kg..  so maybe it's my muscles stretching??
