20weeks

Kiarra

I’m 20weeks pregnant with my first

And I feel extremely skinny for someone who’s meant to be 20 weeks like everyone’s got a bump or showing and I’m just flat at night time I have a little bump like bloat but idk if I should be worried or not my first midwife appointment I was weighing at 58.6 - 4 weeks later at my second appointment I was weighing 59 ? Is this normal or I’m just really worried
