Hi Fattybombom,
If you see the sac where the gynae expect to see, it should be fine. My first appt with gynae today at Week 4 try to scan my wife's sag at where it suppose to be - but because we are still early, we only see a faint black dot on the screen suspected to be the baby/sag, and the gynae said that if this dot is the baby/sag, the position is ok. So, Fattybombom, you are clear from eptoic preg.
