Heavy blooding = miscarriage?

I am on week 5. Been experiencing bleeding two day ago and started heavy bleeding just like period flow since yesterday. Went to see Gynae and got some med and 1 week of bed rest. But so far the med is not working. I am still bleeding very heavily. Really worried that I might experience a miscarriage already. Doc asked me to go back in a week time but wondering if I should revisit earlier, though not sure if I can handle the news. Anyone experienced this and how to stay motivated? I am just on low esteem and in constant tears that it hurts my eyes so badly
