yeah, I agree with JoyRenee.....at 9 weeks, there has to be a heartbeat on u/s......I would wait another 2 weeks, but unless your dates are off, the chances are pretty slim, I am sorry..
If your dates are off then it is possible you're not as far along as you originally thought. But at 9 weeks you definitely should see baby and a heartbeat. The only thing I can think of is that your dates are off.
