Congratulations on your pregnancy!
My midwife transferred me after I gave birth to my first (not at home but at a freestanding birth center...) due to a post partum hemorrhage. After such a great birth experience, this seriously sucked -plus, the hospital ER was a total nightmare. Long story....
Anyway, when I became pregnant with my second, I, like you, was a little nervous. I heard what my obgyn (I visit him between pregnancies) said which was ARE YOU CRAZY? YOU WANT TO GIVE BIRTH OUT OF HOSPITAL AGAIN?? etc etc and then I basically decided - yes!! because I don't want my child born in a hospital. There is a greater risk of a pph happening if you have one once, I know this. But to me, a positive birth experience was the most important thing. I accepted any risks.
When I met with mws the second time around, I asked them all what they would do to help me avoid pph this time. They all had a lot of really good info - and all of them said I could do a homebirth with proper nutrition and post partum precautions.
When I selected my midwife, she helped me work through the last remaining doubts/fears I had about the complication happening again. She outlined the "game plan" for after the birth. So going into the birth, I felt really good!
After a WONDERFUL homebirth (I'm so glad I did it!) I did get a little worried about bleeding again - and I still bled more than normal - but because the midwife had planned for it - she effectively managed the bleeding. And I got to stay home with my sweet baby - no transfer!
My advice would be to talk to all prospective mws about your fears - find one that you connect with - and then during the pregnancy continue to work through them so that you can release them before birth time!
