Hi, my name is Brittany I am 20 years old I have a 17mth old daughter. I have never been regular with my periods so I startd BC to get regulated. Well I am 2 weeks late and I began spotting it was a light pink sometimes I didn't even need a tampon. This went on and off for about 3 days. Then I completely stopped and I wiped today and there's a light brown discharge. I am cramping horribly, lower back is KILLING me, crazy headaches and very tired lately. I have unprotected sex with my fiancé. But my periods weren't quite regular yet. ANY SUGGESTIONS LADIES?
