Almost 15 weeks

Veronica

I’m almost 15 weeks and I was super super fatigued during the first trimester and now I have all kinds of energy is this something normal?  this is my first pregnancy so I am not sure. Also, I have not felt the baby. Is this normal as well?  I go back to the doctor in two weeks. My last check up everything looked really great but I just don’t feel pregnant and no weight gain yet should I be concerned?
