Hi, Thank you for asking the question. 
What is the timing of your menses? there can be a possibility this is a bleeding of menses, if yes, this should stop within 3-7 days, any vaginal bleeding for more than 10 days, is pathological and should be worked up, provided that the bleeding is very small (compared to menstrual bleed), if bleeding is severe or usually more in amount then you shouldn’t wait and see a gynecologist. 
Thank you.
