Advice on changing vch barbell

Lily

So I’ve had my vch piercing since the first week of January and I absolutely love it!! I haven’t had any type of sexual relationship with anyone since I’ve had it so idk how it’ll be like during sex. But I feel like the barbell is unnecessarily long and I want to change it. Right now it’s a 14g but would it be okay if I changed it myself? Or should I go into my piercer and have her do it? I don’t want to take it out and then not be able to put it back in
