Hardly gained any weight entire pregnancy. 32 weeks, please help!

I’m currently 32 weeks 3 days, and I’m 64kg ( I’ve only gained about 10 lb equivalent) .When I started my pregnancy, I was about 62kg. I literally look the same and feel the same. I do notice I get super tired right now, and all my blood work has been ok etc. In my previous “life” I was super athletic and not sure if it’s changed my ratio of fat/muscle, and I’ve just lost muscle and that’s replaced my weight in fat? Currently I’m eating around 2500 calories roughly

Has anyone experienced something similar? I really hope the baby isn’t too skinny? The last time I had an ultrasound was 20 weeks but really would like to ask for another scan if that’s the best way of doing it??

Sorry this is my first I literally am clueless on what to do?

Thanks for all the help everyone 😞🤰🏻
