Thanks for your quick reply...
I could not write more in the previous question because of the world limit.
Since then she continueously has blood coming out from her vagina. sometime there were blood clot as well. We had 3 ultrasound altogether and the result showed that the baby was ok. infact it grew bigger since the first ultrasound and the heartbeats was better (145 beats per minute).
the rubber that left inside was only the top part of the cover (it was torn, not the whole thing).
she had the miscarriage 2 days ago (two weeks since she had the brown patches). after two weeks bleeding, our obstetrician order us to do another ultrasound. the fetus dropped to the floor when we about to go to the ultrasound place. She had the currette done yesterday.
