I found that... maybe it will help.
((((((((((silver_queen))))))))))) from what I've heard... clots can be different colours (black, brown, or red) during your period. Beyond that though... I'm not much help. Have you ever had an infection? It could be a yeast infection (smell) I think.
I'm not a doctor, but thought I'd try to help. When is the doctor's appt?
