16 weeks exact today

Friends, I'm a bit worried thinking of the growth of the baby. My last scan was in 12th week.

it's been a month after that we did the NIPT in13th week.The results came back good and we now know that our angel is a girl. However, I'm having this unnecessary tension now...I have been having bloating from my 6th week...and my tummy looked like 5th month from my 6th week. now I'm 16 and I dont find any difference in its size.is that normal?

also I gained 5 kg in first trimester but in my 4th month it's been only 1 kg increase.......

and I just dont feel pregnant at all..... :(:(:(

need your words.....
