Anyone Else Having This Problem? Normal Or Should I worry?

OK so turns out at our gender reveal wer are having a little boy!!! I was really wanting another girl but I'm super excited and over joyed I will have a boy.... my question is.. I'm almost 20 weeks and I still haven't felt him move AT ALL! and he is sitting funny. his head is facing my belly and his but is facing out and he is laying face down... had anyone else been having this problem of not feeling the baby? and what do I do if he don't turn around?
