Anyone else with extremely high hcg levels??

Samantha • Married to the love of my life. Healthy 1st baby (boy) 10/07/14 after a long road to pregnancy. Couldn`t be happier!!!!
So I am currently 4w5d pregnant. I had my hcg levels taken twice last week the first one can out at 51,215 and two days later it had gone up to 73,980!! Yeah that's 74 thousand! My dr is concerned I could be having a molar pregnancy and so I am heading for an ultrasound in two days and more blood work. My progesterone levels are perfect. I'm worried that it is a molar pregnancy and can't seem to find any good info online on what my situation is. Is there anyone out there who has/had extremely high hcg levels and had a healthy baby?? X
