You weight is probly not to big of a deal. Like I always say weight is not and issue till its an issue. Like heart attcaks diabetes.But acually at ur hieht ur not doing bad in the wieght factor. Im the same hieght as u are and weight 130. And acually u and I are brobly either under or right on weight to our hieght because they say a normal girl of 5'5'' should averge the weight of 130. So really its up to u . If u do feel like u need to go for it. And the fact that u have muscel will help. Because nothing burns unwanted fat faster then muscel but realy I would say u dont really have to worry. Cuz its not realy and issue.

Get your height measured again and then ask to have your bodyfat tested with calipers. That might give you a clearer understanding of where you're at physically.
