I do not get a bump at all

I keep searching and can’t find anyone that goes through this either. Last pregnancy I had my son a little early at 35 weeks, and had no baby bump- flat. This time I’m almost 20 weeks and still flatter than a pancake.

Does anyone else get no bump? Also, my son was actually ahead for his gestation when I had him, so it’s not a small baby issue. I was very sick last time with HG, and I have it again this time but this time I’m able to keep food down and I’m throwing up less. My doctor is very floored and anyone I talk to, no one understands it.
