Should I worry?

Went for our 12 week scan in Nov ( on the the 10th ) and the radiologist said growth has stopped at 7 weeks and Miscarriage was imminent.

Nov 15 and 16 heavy bleeding and clots.

Nov 16 to Dec 10th heavy spotting on and off.

Physican said it can go for another few weeks, no signs of infection.

It's now January 3rd , no period.. having brown / grey stringy discharge on and off and some light spotting on and /off.

Worried about incomplete Miscarriage? Infection?

Doctor didn't seem concerned ? See him again Jan 13.

No pain, no temp, it's infrequent. But gross.

Really wanting to try again(*_*) also had a miscarriage in April and a D&C then at 6 weeks.
