We have lucky enough to be successful on our first round of iui. We went for our 8 week scan yesterday. The consultant said heartbeat, blood flow was looking good, however the gestational sac was slightly smaller than we would of liked. It took me by surprise at the time and I didn't ask any questions. What does this mean? Is this an indicator that im going to miscarry? I'm terrified. Has this happened to anyone else. I can't speak to the consultation again until Monday.
