alright, so i'm 15 years old. i didn't have my period at all last month, but i had my period 2 weeks ago, and besides a little spotting, it stopped after 3 days. now 2 weeks later i wipe myself, theres blood. i looked in my underwear, blood. and its more reddish then usual 2, which is weird. but honestly, i just had it 2 weeks ago, and yeah for a short time, but still, what could cause this? stress? cuz i have been REALLY stressed out lately....
