Threatened Miscarriage

I need some positive stories ladies, and some negatives so I stay grounded.
I'm 6+2 weeks pregnant and have already had two substantial bleeds resulting from a perigestational haematoma (a very large clot on top of the gestational sac). I've had a successful pregnancy previously following a similar diagnosis. This time there's been way more blood and my HCG levels are rising very slowly. For example, on Friday they were 11000, today (4 days later) they're 26000. They should be nearing 44000.
Has anyone with slow rising HCG levels gone on to have a successful pregnancy? I'm in limbo until my next scan in 9 days.
