I'm only 16 and I've had my period for 5 weeks nearly 6 weeks and it's constantly heavy, it acts like it's going away but never does. It's the first time this has happened and I'm worried. I don't understand and I'm confused. I took contraception pills but I have been off then for a few days now. I thought my period would of stopped by now but it hasn't. If someone has an answer to this please let me know.
