What do i do im really broody!!?

im 21 and im really broody! i have been since i turned 20. but my partner doesnt want kids till im thirty (well thats how he feels at the moment) and i know logically im not in the ideal position to have a child for example id have to move house again and get another job etc but i still get insanely broody and jealous whenever i watch programmes about pregnancy or when my colleague and manager talk about there pregnancies. is there anyway i can control this?
