Hi I am 27 years old, I am sexually active. I have been getting regular menstruation in the past year, however my period is now a few days late. In the last few days, I have been getting very very light spotting (brownish spotting) for  5 days then it stopped. I did a pregnancy test and it has been confirmed that I am NOT pregnant.  I want to ask: 1) What causes this sort of spotting and 2) Could this be symptoms of STDs?Other factors that I have: recently I have been stressed about exams and have changed my diet slightly i.e. less carbohydrate intake, could these influence why I have been getting spotting?Your answer would be greatly appreciated.Thanks, C
His think I have understood your concern. Your spotting and delay can be related to hormonal imbalance. Egg formation process might be getting delayed, which in turn causes delay in periods. Irregular spotting can be due to in-synchronous shedding of endometrial lining of uterus. Unless you have pain and vaginal irritation it can not be called as STDs. Please follow safe and protected sex practices. And your symptoms are not due to STDs for sure. I will suggest a healthy diet and regular exercise regime. Include fruits, salads, vegetables in diet. I hope this answer helps you. Thanks Chat Doctor.
