Retained placenta troubles!!!!

14 days after my princess was born silently into the world I was bathing my niece when I felt like I was wetting myself! Luckily I was in the bathroom so I jumped onto the loo and too my horror I was bleeding... Not just a bit though I could have filled 2 pints easily! There were clots the size of my fist. My mum had a retained placenta with me and knew exactly what It was! She rang 999 and an ambulance blue lighted me too yeovil hospital. I was admitted AGAIN to labour ward. Too the exact room I gave birth too Sadie in!!! :( as if it wasn't hard enough! They put an iv drip in my arm and the gynaecologist came in to see what caused my bleed! He could see bits of Sadies placenta still inside me! They kept me in over night and kept me on an antibiotic drip because the placenta was rotting away inside me and caused a massive infection!! The next day I was promised too have a scan by 12pm! 3:30pm and they took me down too scan!!! They found bits of her placenta 17mm bits and told me that they want too put me on a full 7 day course of antibiotics but they were happy it would pass naturally! I requested a full gynaecology scan as I wasn't convinced it would work!! A further 14 days later on the month anniversary of my baby's sleeping birth I had my scan! The sonographer looked  worried and told me I have the placenta bits still in there and that my womb wall should be 11mm and mine is 21mm!!! She sent me too the gynaecologist as a matter on urgency!!! The gynaecologist told me that I would be taken down to surgery on Monday or Tuesday! So here I am waiting for my scan... Once again I feel let down that they left me too pass her placenta!!! After 1 month it's still inside me :( psychologically its nasty knowing I'm carrying around my sleeping baby's placenta bits!! But there is nothing I can do expect wait for them too take me to theatre on Monday or Tuesday!! I will keep you posted on my surgery! If anyone else has experienced any problems with after care please let me know so I can relate too you, thanks :) xxx
