low hcg and I heard the heartbeat any success stories

Pamela
hello, 
my beta is taking about 11 days to double. it was 7500 on sep 2 and on the 8th it was 10,187. I was told to expect the worst but had an ultrasound and I saw the baby dancing around with a heartbeat. wondering if anyone has a success story since most women in this situation seem to lose there babies a few weeks later. the heart beat was 134 beats per min.
