Dear all, my wife is 6 weeks pregnant, we went for a scan yesterday, all we can see is a small sac about 0.48cm which according to the therapist it should be twice as big as it is now. No yolk or fetal pole is found yet. My wife and I are extremely worry and panic, she is not willing to surf the web for more information as she is too afraid to read something bad. Can anyone tell me whether we should be worry about this? We never had a baby before, this is the first time after we have been married for 2 years. Is this a common case for pregnant woman?
