Yes as Merline said anomaly scan will help you to know how is your baby's health to some extent.

Pregnancy is we believe and we fall in love though we haven't seen or touched yet. Doubts are common but you got to believe that the baby is doing fine inside you,  Soon you will have movements so you will know the baby is active or not active but again you can fret over it. Relax and enjoy this phase and be positive.
