so i'm confused. i just ended my period(well i think it was my period) it was 4 days and it's usually 6. i had absolutely no cramps at all and i usually can't walk because of the cramps i get. and it was dark brown when i got it and then it turned into red for like 2 days and then back to brown. and i was just so nauseous when i was laying on my back or side and i just threw up... what's happening.
