I am on my period, but when I am sitting on the toilet seat it is coming out with a good flow, but in sanitary pad it's nothing, not even a single drop. I got my period yesterday 1st it was very dusty, powder type, then it was coming out in clots, lots of clots, then when I went to change my pad I saw normal amount of blood came out in pad. But today morning when I went to the toilet I saw no blood in pad, only when I sat in toilet seat it's came out, why it is happening? Please help me
