A member asked:

Light brown discharge for 6 days and then one day of dark brown discharge, just finished cephalexin prescription, also on trinessa (norgestimate and ethinyl estradiol). normal?

Breakthough bleeding: old vaginal blood and mucous, no necessarily related to cephalexin. If dischage continue for 2 more days call your GYN and get a pregnacy test if having unprotected sexual intercourse.
