Is it normal to feel all these changes?

Hi ladies

This is my first pregnancy. According to my LMP I'm 9 weeks.

I am at a point where my body feels so different every day... one day I'm extremely nauseous, the next day I'm not at all and so forth, every once in a while I feel like my periods coming any minute, some days I feel completely normal and other days my tummy feels so wierd and different or my back hurts.

Is this normal? Especially so early on? Would you feel all of the changes??

With my tummy it's as though I feel everything changing!
