Anyone who had retained placenta?

I haven't posted in quite a while, so first off for my contact Adelaide and I are doing great, 4 months along and growing like a weed! Motherhood has been lovely and I appreciate every moment of it.

Now that being said, I'm already starting to look towards baby number two since it took us 3.5 years to have this lovely baby (though I wont start trying til at least the summer/fall).

Twelve days after birth I started hemorrhaging, I called 911, and lost about 4-5 pints of blood in the ER before they realized I had a very bad case of retained placenta and got me into surgery. I decided not to get a transfusion, cause I was coping fairly well with the blood loss, and didn't want to risk contracting anything/passing it on through breast milk. Recovery was very very slow, and it took almost 8 weeks after for me to feel normal again.

So now I feel great, and am looking to the future, but my big fear now is having the same issue happen again. So for anyone out there who has had a retained placenta, and a subsequent pregnancy, was there anything extra done during your subsequent pregnancy/labour to help prevent retained placenta? And also if you did have a second child, did you have retained placenta again (as the rates are much higher if you've previously had one).
