Hi,I am writing in regards to my youngest sister,who is 17 yrs old.Several months ago she started having very heavy non-stop periods.After that went on for about a few weeks,my mother and her decided to put her on the Depo shot.This decision was made since my other sister and I had both used the shot and for us,our periods stopped completly before the next shot was due.Anyhow, this is not the case for my youngest sister.She is still having very heavy non-stop bleeding and this has been going on for months.She and my mother have brought this to their doctors attention, but he just says that this is a normal side effect.I have looked on the web and the only info I can find about heavy long term bleeding is for those who have decided to stop the Depo, but nothing relating to those who are currently on it.My sister has also lost 10 lbs since she started the Depo.I did find some forums of others who experienced this as well.But what about the blood loss?She's been bleeding for quite some time.Since months before the Depo.Any idea what this could be?
