Brown discharge and blood clot at week 6. Is it worrying?

Just went for HCG count check this week and all was normal except for spotting and brown discharge. Was asked to take 4 duphaston tablets daily. Saw a small dark coloured clot flushed out today with same brown discharge again. Was initially reduced to light spotting but the dark brown bleeding seems slightly more on pantyliner now. Is it normal? Will try to see a gynae later
