30 weeks and its just now starting? lol..consider yourself lucky,lol. As the baby gets bigger and takes up more room,your other body organs basically move out of the way and in the case of the bladder...there is more pressure on it now.
I believe that by 30 weeks most babies are in the downward position with head facing down.The doctor will probably be checking for position at every appointment now.The bigger the baby gets, the less room they have to move around so its better if they are facing downward already at this point. Good Luck! :)
