kristi how is BFing going? If you have retained placenta your milk supply can really take a hit, because the placenta coming away is one of the things that causes the hormonal surges that bring your milk in.

Have you been doing to much recently? My bleeding had slowed right down at 3 weeks and i went out for a longish walk, got stuck across town with the buses not running and had to walk back with DD in the wrap, and got myself over-tired and my bleeding came back on again red and stayed for another few weeks going through the whole tailing off thing again. My MW put it down to the long walk and stress.

Give your midwives a call and talk to them about it, see what they say.
