Never hurts to check with your OB. I thought it was nothing and it turned out to be a yeast infection.
They say a thin, milky, mild smelling discharge is normal throughout pregnancy. Its purpose to protect the birth canal from infection and maintain a healthy balance of bacteria in the vagina.
Its very normal im 34 weeks and my doctor told me my body is just preparing you for labour its fine the only time you worry is if it has a odor or if its pink- ish
