Period from hell- I've been bleeding for 3 weeks?

Ok- So I'm looking for some re-assurance or advice. And yes I am going to see my dr, I'm just waiting to get in.

August- discover we're pregnant YAY

Nov 2nd have a routine scan but baby measures 9 weeks. Nothing looks amiss though- just a missed miscarriage

Nov6thD&C- all goes well bleed for 2 days only

Dec 13th we're told it;s partial molar and the blood tests start.

Mid dec 1st regular(ish) cycle since D&C- lasts a week

Jan 15th start another bleed. LOTS of INTENSE period pain for the first three days, then it peeters out for one day, then the bleeding restarts and still happening (todays the 1st Feb).

The colour of the blood is now very dark- almost black, but I don't have any period pain anymore.

Oh- and my blood tests have shown a HCG level of 0 since late dec.

Thanks for your help in advance!
