Hi! I need your help .. I just got my period today as suspected although it's very light and brown , however when I clean myself it comes out red. I have been taking doxycycline Hyclate for acne for 2 months now and it didn't affect my cycle last month. I was sexually active about 3 weeks about but used protection. Why is my period is light ?!?! Also I have been having cramps and normal period symptoms
