does birth control make your boobs grow?

So i’ve been struggling with body positivity for a while because of my boobs, it’s hard because i’m not even a 30a(which is the smallest size offered in some stores). I was considering starting birth control for the sole reason of regulating my period and helping my boobs grow.

I have a few questions tho

1- do ur boobs actually grow???

2-will i get acne from birth control (i currently have really clear skin and don’t know if i wanna risk it)

3-will i gain weight? (i used to struggle with anorexia and I don’t want to relapse)
