Hello,
Welcome to ehealthforum and thanks for writing
Vaginal discharge which is white and is not associated with any foul smell or change in colour is a normal phenemonon.It increases during ovulation,excitement,stress,pregnancy etc.It might be an ovulation symptom in your case.
But if there is any other associated symptom as pain,burning,rashes,foul smell then it can be indicative of infection.Observe for any changes and in that case consider visiting a Gynaecologist for evaluation.
Take care!
