Really Short Period

[atina6]

For the past few months my period has decreased to barely just over one day. I have always had short periods, around 2-4 days since I started but recently they have been one day. I know i'm not pregnant, and have no problem with lateness or pain so is it just low estrogen levels? and if so what could cause this?

[ummmm]

Lucky you.....I have this sometimes. Mine last usually 2/3 days. Sometimes just a day. About twice a year I get a heavy one. So I think it's normal
