The important thing in math is to know that it is cumulative- that is that everything you learn depends on knowing what came before very well. You may have a problem with not knowing the basics.
What I'm saying is you should worry about really learning and not the grade. But why not talk to your teacher and tell her that you worked very hard but don't feel your grade reflects that? Maybe you can do some extra credit. It can't hurt to ask for help. You really need to know your basic math skills, which is the important thing about studying math, anyway.
P.S.See the reason you did well at geometry may be because geometry doesn't depend on basic math skills. It's a whole other subject. Also, you may simply like it more. Anyway, you can do math, judging by that.
