Is Extreme Bleeding After Getting The Coil Fitted Normal?

Hello... I Had The Coil Fitted On Wed The 26th Of Jan 2011 And I've Been Bleeding Since... I Also Had The Implant In Which Was Only Removed On Wed 9th Of Feb This Month, I Understand That The Bleeding Might Be Different To Other Case's But I've Got Really Heavy Now But With No Pain What So Ever... I Literally Went Through 7 Sanitary Towels Just Yesterday, I'm Starting To Worry, I've Checked My Threads And There Also Fine... Any Ideas What The Problem Could Be???... Thanks...
