Jane :hugs:I have experienced two early miscarriages. My Angels were 5-6 weeks so a little smaller than your Angel. I had quite strong period type pain for a day and then there was very little discomfort. The blood loss was heavier than a *normal* period. However the blood loss was minimal in the first couple of days.
Your angel was so very tiny and those stringy bits, tissue and clots are difficult to identify. I imagine that your doctor will do another u/s and check your levels but it does sound that your miscarriage is progressing.
It helped me to put a hot pack on my back and on my belly - you may find this helpful too. Drink lots of fluids and rest as much as possible. Your body is working very hard...

I am so sorry again Jane for the sadness and pain you are feeling.
