I am 19 years old. My cycle has always been very erratic (though never shorter than 32 days). I normally bleeding for at least 8 days. My last cycle was 68 days (approximately 34 days late, but then, on December 13, I started bleeding lightly (which is unusual) then heavier and then light and heavy again, etc...but I am still bleeding. There is no pain or clots or any other symptoms. What s going on? Do I NEED to see a doctor? Or should I keep waiting? Please help!
