My last period was 5 days instead of 7 the first two days were like normal flow espeically when i went pee on the first day like u know, and also i had horrible cramps on the first day. I had clots too, everything was weird but like it was different than my period. I have a 7 day period all the time and its almost always heavy. That time it was light, towards the end mostly brown blood. (My period cycle has been wacky these past few months though) im fourteen years old got my period 2 months before i turned 13
