23 yr old, I had unprotected sex two days before and one day after ovualtion. Well 15 days after ovulation, 2 days after missed period I took 2 pregnancy tests. First was negative, the second, that evening was a faint positive. This is/was my second pregnancy and I did notice some signs;however, the next day I had brownish discharge which I was believed to be perhaps implantion bleeding. Well now I'm having red mixed with brown light to medium flow. I'm going to take another test after I stop bleeding. My question is: Does this sound like an early miscarriage, late implantion or could this just be the lining clearing itself out? & Could I still be pregnant?
