Bleeding with HCG draw

Emily

I am currently 5wks 4days. A few hours after I woke up this morning I went to the bathroom and when I wiped it was light pink. No cramping or any pain. I continued to spot all day and now it seems to be turning darker and thicker. I did call and they had me go in to get my HCG drawn which was 990. This seems low for almost 6 weeks compared to my other pregnancies. I know this is on the low end of normal per all the online charts but was just wondering if anyone had a similar situation turn positive? I’ll go get drawn again in 48 hours but I’m feeling pretty down 😔
