baby movements too low..

Hi! So I'm currently 5 months 1 day! The thing is that I've been feeling light movements of my baby, but way way too down!! Like one finger and half down my belly button .. is that normal? Should I worry!? I feel like it's too way on the bottom!! Like if the baby is trying to come out! I have a 7 year ok son and this never happened while pregnant of him..I have a very delicate pregnancy.. treatened of abortion.. I'm doing better now ! Thanks god!! But that's my concern now.. is it normal?
