Miscarriage big blood clot

I have a miscarriage recently at week 9. But till today I still bleeding on n off for 3 to 4 weeks. I opt for medicinal instead of D&C. 2 weeks ago, I have flush out a big chuck of blood clot, I have went for a scanned n confirmed the foetus has already expelled out from my body. However, today I have passed out a big blood clot again like a liver size. Is it normal? Wanted to see a gynae but my gynae clinic closed on weekends.
