Tmi picture!! Blood on toilet paper

I fear I’m having a miscarriage 😔💔 on 11/30 i went to my first ultrasound. I had irregular periods but following lmp i should’ve been 7wks that day. Well the baby seemed smaller but the doctor said he could see a heartbeat (transvaginal u/s). It took him some time to find it though. After that visit i started spotting. I would wipe and have brownish blood. But only when i wipes. There was none in the toilet. And then i started getting light cramps. Didn’t really think much of it since i had them ever since i got positive pregnancy tests. But last night i went into the er because i had read lots of stories indicating it could be a miscarriage. They drew my blood and said my hcg was over 5k. So they did an ultrasound both abdominal and vaginal. The doctor later came in and told me they hadn’t been able to find a heartbeat but maybe it was just too early because the baby measured 6 weeks (don’t know exactly but wasn’t surprised since we took clomid so i might’ve ovulated later) she discharged me saying i had a threatened miscarriage. Well ever since the u/s yesterday i put a pad on but there’s barley anything on it. And i just went to the bathroom and saw this. No blood in toilet. Could i possibly be having a miscarriage? Should i go back to the er?FTM and Monday doesn’t seem to get here soon enough to see my obgyn

*The dame doctor who treated me last night was the one who told me my hcg level wasnt in a pregnancy range the first time i went in for cramping. I later found out my hcg there had been 17.4. But at my obgyns office that same day it had been 50.1*
