Quoting My boys = My life:" So please tell me doctor smurf.. Why did I pass a placenta 4 inches in length 1 inch wide? Give me a chart specifically stating placenta sizes.. Not sacs PLACENTA"
When i had my U/S last pregnancy, I was much earlier than expected because of a funky cycle. At 5 weeks via U/S dating, they had to zoom in all of the way to barely make out a tiny itty bitty dot of a circle that would eventually turn into a gestational sac with everything inside. Now if it was that small that the U/S had to zoom in all of the way and had a miscarriage at that point, there would have been blood and clots, but there's no way i would have recognized anything baby-like inside of it.
Also, when i had a miscarriage at 5 weeks, there was tons of blood, but nothing identifiable.
There's no way you could have been 5 weeks pregnant and passed something 4 inches long. Your dates must have been off.
