Help!! Bleeding at 7 weeks!

Two days ago I had a gush of warm, dark red blood during my exercise routine. I exercise Monday through Thursday and have been religiously since before the pregnancy. It was enough blood to leave a large spot on my underwear and to drop into the toilet (sorry, tmi). I am so worried!! I obviously called my doctor IMMEDIATELY to find that she wasn't even in town. The midwife or the PA (I can't remember) who also works in the office ordered some blood work to check my hormone levels but didn't even see me that day!! I literally got my blood drawn and they sent me home. No exam. No ultrasound. No doppler. I go back in tomorrow to check hormone levels again to make sure they're still normal and not dropping. I have experienced ZERO cramps. I didn't even cramp when the gush of blood happened; it just happened. I'm frustrated that I haven't been seen. What could cause this? Should I demand an ultrasound?? I know they deal with this all of the time but I don't and I'd like to know the baby is ok! We TTC for a year and a half before our BFP and I would be devastated if something were wrong 😭
