I had started my period yesterday after track practice... but it was insanely light and had brown clumps, but there was still red blood. I know that towards the end of your period that is normal but is it normal the first day ? I woke up this morning expecting my usual heavy day, but it was still insanely light with brown clumps and there was nearly nothing on the pad.. Is it normal for my period to be that way the first day or is something wrong?
