Hi I Visited My Gp Today Due To Having A

Hi I visited my gp today due to having a baby 5 months ago and my episiotomy scar not healing right, she checked my cervix which she said has a red patch on but she doesn't think it's anything to worry about but I'm being reffered to a gynacologist to be sure. However I'm now worrying, what could this be, I'm only 20 years old.
