I m 18 years old and freaking out. At first I had this odd smelling light brown discharge, it didn t cause cramps and there was A LOT of it. Like, more than my usual period. Now, one week later, I m having dark brown/ black clumpy, what I m assuming, discharge. I ve read everywhere and they all associate brown discharge with implantation bleeding, but I have had no other signs of early pregnancy. I m worried I may be pregnant, but I m pretty sure I m not. I m on the pill and last I had sex was two weeks prior to the weird discharge.
