5 weeks today

Sunday (4 weeks 5 days) I went to the Er for severe pain in my lower back right side, and some small cramping on my right lower abdomen. Right before we left for the ER I started spotting, it went from brown to dark red to brown for a while and the red one time I went to the restroom and now it’s been brown ever since. The pain was so bad I was shaking and had a heart rate between 115 and 120. I had hCG levels taken and they were only 96, I’m going to get more labs taken later today to see if it’s doubling. Anyone ever had low hCG or had this happen and everything turned out fine?
