High HCG?!

Mallory
I went through an ectopic pregnancy about 6 months ago, but I found out that I am 6 weeks pregnant last week. I went in to get an ultrasound, so I could make sure it is in the right spot this time. I saw a little "baby" and heard the heartbeat. I also got blood drawn and got my results of my HCG back. It says it's 86,536. That is almost 30,000 higher than anything on the charts says it should be at 6 weeks. Anyone have experience with this or still had a successful pregnancy after a high HCG? Starting to worry!
