baby girl with pubic hair HELP???

Haley
My 5 month old daughter is starting to grow pubic down in her private area 
Is this normal?? 
Do i need to be worried? 
Ve been ready alot of parents says its not normal and could be early puberty that can cause stunt growth 😰😰 
Im worried it might have something to do with planned parent hood giving me the depo shot not knowing i was prego with her and all the extra hormones she got 
Im calling to call her doctor but wanted to know if any other mamas have seen or heard of this??
