Bulking up

Hey FB fam!!

I feel as though recently I’ve been bulking up and that wasn’t my intention. Idk what to do I haven’t really change any of my eating habits. What advice do ya’ll have for me ??? I feel as though I’m building alot of muscle around my legs my work scrubs feel tighter around that area. My weight has been fluctuating from 116-118 I’m 4’11. I know it’s normal for body changes just I’m scared to get back to the point where I wasn’t healthy,
