HCG Question

Brittny

I'm not sure if this is the right group to post in, but had a question to see if anyone else has experienced this. I have been doing bloodwork to monitor my HCG levels.

My results on Wednesday were 399 went back yesterday and my levels were 710. They say they are supped to double every 48 hours. Has anyone not fully doubled every 48 hours and gone on to have a successful pregnancy? I'm sure I'll go back next week but because of the holiday I'll be waiting longer to talk to my doctor. Thanks in advance!!
