My daughter was pregnant and had a miscarriage, saw what looked like a tiny baby too in the pools of blood in the floor of the ER. Her hormone levels started falling and everything. A few weeks later she was still having pregnancy issues.
We went to the ER and she kept telling the nurse she just knew that baby was still in there messing her body up, that they had to do a D&C, the nurse just smiled and said she was fine, her body was just going back to normal after the miscarriage.
She kept on and on with the nurse and finally said she wanted her to do an ultrasound on her stomach to see what was in there.
The nurse just smiled and went and got the tool. When she came back and started it up my daughter's heart rate was about 80 and her tummies heart rate was 125 or something like that. She had only miscarried one of a set of twins.
She was about 16 weeks along because the tool would not have picked up the heart beat so easily if she had not been so far along.
The whole staff started coming in and looking at the ultrasound. The doc asked her permission to write her case up in the AMA journal. Since her hormone levels had dropped it was unusual.
So, there are many things the female body is able to do and to overcome.
