To easy of a pregnancy?

So first to all of the ladies that are having rough pregnancies I apologize. I'm a ftm 12w+6 My pregnancy thus far has been super easy, yes I'm tired, I could even say extremely. I haven't gotten sick at all slightly nauseous nothing unbearable. My boobs have grown but hurt more when I was on my period than they do now. I can eat what I want. I'm not bothered by making or eating any food. I do have foods I prefer now mostly fresh vegetables and fruits. I'm no longer moody. I even went as far as buying a fetal doppler so I could hear the baby because honestly I just feel fat even though I have yet to gain any weight. Is this normal any other mommas out there with me? Should I worry? The dr said everything is fine but I've been ttc for 2+years. Any comments would be appreciated.
