20 weeks and having concerns

yay i finally found the preggy section. Im currently around 20 weeks pregnant with my 2nd girl. 1st pregnancy with the Lap band. I am wondering how things are going to go when the baby gets bigger, im having a real fear that my ports going tro be ripped out by the baby or something.??? Since being preg i havnt seen my band dr at all... tut tut because i really did not want him taking all my fills out. i have 5 mls in there atm and i feel i am eating like a horse atm maybe ive stretched it :S... im watching the numbers on the scale go up and even tho i know im preg it still dissapoints me. I just weighjed myself this morning and im 98kgs im like omg its heading towards 100. with my 1st pregnancy i put on wayyyy to much weight and im just so scared of doing that again.
