For soon to be mom you should take the time to celebrate these amazing changes in your body and this even more amazing moment in your life. The photographs will become a wonderful gift to pass down to your child as an heirloom of your first memories with them. Truly a lifetime treasure. This moment will only come once for you.
Don't be afraid to capture that and celebrate it because I promise you if you don't it will be something you will forever wish you had.
You could print, framed it, hang it and it will be an instant conversation piece whenever someone see's it.
