Am I too big for ice skating?

Hi! I'm starting my new cl in two weeks. I'm going to start learning jumps (just a waltz jump and a bunny hop) and I'm afraid I might weigh to much. I'm 14 5'4 1/2 and weigh 123lbs and I'm worried that I might have more trouble then everyone else doing them. I know I'm not fat just not like stick skinny like most of the girls are. So basically my question is am I too big and will it be harder for me to do things the farther I go on with skating? And also will I lose weight the better I get at skating? Thanks for answering! :)
