Postpartum bleeding.

My di/di twins were delivered vaginally on March 23rd. Prior to our discharge, I asked the mother/baby nurses how long I could/should expect to bleed, and was told 10 to 14 days. I am now 19 days out, and still bleeding (heavier than a light period), and today I passed several egg sized clots.

For other twin moms who delivered vaginally, how long did you bleed for?
