Inverted nipple at age 18, is it worth checking out?

Hi everyone, I apologise if this isn't the correct place to ask. A couple of months ago, I noticed that my left nipple became inverted. I can gently encourage it to come out, but it appears redder and wider than that of my right breast. There's no pain or any other symptoms. Is this something worth bringing up with my GP or am I overreacting?
