i went in to the EPU this mornin as i've been having shoulder pains for the past couple of days and was worried of ectopic, despite no other sypmtoms, which nice doctor explained was highly unlikely. She scanned me anyway and we saw the sac in the womb and everything was ok. But she queried my dates as I am supposed to be 5.5 weeks but she thinks things look smaller than that. my LMP was 13th Sep, so technically i would be 5.5 weeks. she's going to scan me in a week's time to see if it's develpoing as it should, should i be worried?? is this normal? aarrghh....!
