Hcg levels / bleeding


I am 6w&1d. Friday I started out with light brown discharge. Well today, I started bleeding red. So I went the E.R they said they labeled it as a threatened miscarriage since I was bleeding and they didn’t have an u/s machine on the weekends. My HCG blood levels came back as 1700. Is this low for 6w? I have my OB appointment Monday so I’m hoping my HCG will rise.. I have low cramping and back cramping. It seems I’m not bleeding Brown now instead of red like earlier. Anyone else have something similar?
