I'm the same size as you and this one is my 3rd. I only felt movement a week ago and I'm 22 weeks today. DH hasn't really been able to feel movement till about 26/27 weeks but its worth the wait
I also hear you about not looking pregnant. I see all these gorgus bumps and I catch myself saying 'I wish'. But in the end we all have beautiful babies.
No advice on the club feet, sorry.
Best of luck with your pregnancy oh and a big on having a boy. We are too
