Should I change my bellybutton ring?

An

I got my bellybutton pierced June 12th 2017 and have never taken out the jewelry I have in. One of my friends told me that ideally I would want to wait 6 months to change it out but I feel like I’ve had it long enough I can safely change it. I occasionally still get crusty shit on it and can sometimes squeeze out this white liquid (it’s not puss). Do you think I would be okay or should I wait??
