First pregnancy totally normal.
You prob won't start showing until 20+ weeks
With my first I started showing around 18 weeks.
With my second started showing around 15/16
With my first pregnancy, my baby bump didn't start showing until about 5-6 months. One day it just 'popped' out. Your bump will come :)
Its totally normal every person is different...
I am on my 4th pregnancy and currently 21 weeks and hardly showing yet...
Its been the same way with all my pregnancies and all my kids have been healthy :)
Dont stress over this right now youre fine and enjoy the no bump while it lasts cus then when you get huge it gets a little tiring after a while lol Congrats on the baby by the way :)
