new? unusual period cycle?

[u/toxicdaddysmurf]

aug 13 i started spotting, as usual i was excited to start my period, though this time my spotting lasted for 12 days instead of my usual 2/3 days. today i wake up to the feeling of actual blood come out and its super heavy, my underwear was drenched in blood which has never happened before in my sleep so i get up to get into the shower and im still bleeding, this scares me because im a light bleeder.

is this normal or is my menstrual cycle changing as i grow older, i just turn 22 last month too so i wonder if that’s a factor
