aww bless you. sorry im not very good at remembering individual circumstanes but have u had a previous ectopic? with this baby i put the scan off as long as i could doctors were pushing me to go but i just didnt want to was so sure the pregnancy would fail, after the scan tho thye offered me fortnightly scans (which i actually turned down) i know immvery odd lol. so u might find once uve been for the one on the 21st they will do mre for ur reassurrance. theyre probably just going witht the 21st as from experience the hb is definatly detected by 7 weeks whereas if u possibly ov'd a little late a 6 week scan might not be able to see yet and would cause unnessisary worry. im not sure what to say to reasure u hun, maybe just try to make plans for the next few weeks to keep u busy so that time goes quicker. i know its had but all u really can do at the moment is try not to think about it too much, sorry if that sound slike rubbish advice. maybe theother girls have some better ideas xx
