Bleeding 7 weeks 4 days

I'm so nervous. I just had a miscarriage July 16,2015 and I noticed a brown maybe discharge 2 days ago but only after I wipe. Nothing in the toilet but urine. After that a very tiny blood clot, again only after wiping. Then it was pink. I went to the E.R. they say everything is ok. Baby's heartbeat 144bpm. Yesterday and today, slightly bigger blood clots, but not huge. Brown and red on tissue after wiping. It's now going into the toilet after I pee and dripping on a pad. Before it was only visible after wiping. No cramping but I did have a sharp pain in my right leg yesterday at work. Anyone else experiencing this? Should I expect a termination? I'm so nervous and scared. All I can do is continue praying, trusting and believing God.
