Thanks for consulting. I have carefully worked through your case, and I can realize your health worries. Being your physician, I assure you not to worry as I will take care all of your medical concerns. since it is an one time even there is nothing that need to be worried. slight bleeding may some times give pinkish spotting. it may be due to some infection or inflammation. it is not a matter of concern until it annoys you or the frequency or severity of the incidence increases. Hope it helps. If you need further, detailed and quick assistance related to any health issues in future, feel free to ask me a question directly from my profile. Have a wonderful time ahead. Best Regards! Dr. Arunmozhi varman
