I am 28 years old and i've been sexually active with my boyfriend for a year now. There was a time we used to have sex almost everyday but a time came where we do it once in a month due to distance and work. Around february this year, I treated infection, same thing in august, which came with serious pain during urination which I also treated with ciprofloxacin, metronidazole and flagyl. But for some days now, i've been having pains in my lower abdomen and by yesterday (27/11/2019, I started seeing green come out with my discharge and now i'm on medication again. Why does keep recurring?
