I finished my doxycycline treatment. there is still a discharge little to nothing. it's mainly in the morning. is it ok to have unprotected sex?

STD: If you were taking doxycycline, the presumption is that you were being treated for a sexually transmitted disease. The Doxycycline took care of the infection. Now if you have unprotected sex, you are exposing yourself to the conditions that caused the first infection and can be reinfected. This may cause problems later when you are planning to start your family.
