Spotting turned to bleeding at 5 weeks and 6 days.

Hey guys. I'm 6 weeks today, but last night I felt a bit uneasy in the stomach. I went to the restroom to throw up, but nothing came. All of a sudden I felt something trickling out of me. To my surprise, I was spotting. The color then changed to red from light pink. At that point I was completely freaked, and ran to the ER. They confirmed that my hcg level, which was 332 last Wednesday, is now 10 860. I was also able to see the little peanut via ultrasound. I am still a bit worried. However, the bleeding has stopped, and I see my obgyn today. Hopefully the hcg levels are even higher. Has anyone experienced anything like this?
