mrsN If you're sure of your dates, then I would go ahead with a scan next week - I've been for two scans at 7 weeks and you can see a little bean shaped blob with a little flicker. Of course, if things aren't going 'to plan' then you will be sent away for another week/two but, weighing things up, would that make you metal much more than you already are? If you are 'happy' for want of a better word to wait until 9 weeks then do! I couldn't do it though. Or, y'know, I could if I absolutely had to but I didn't have to thank goodness
Have you and DH had any genetic testing? Perhaps something to look into having had 4 blighted ovums.
pebs Jeez, talk about a rock and hard place! All I can tell you is what I would do... And, in a rational state of mind, I would recognise I am exhausted (physically and emotionally) and concentrate on getting myself to a better place for both. Perhaps only for a couple of cycles. Meanwhile, you would hopefully have been seen at st.marys and had the tests done that you can't have when pg...
But let's face it. We're none of us rational during these times. I would, probably, just try again straight away, especially as in your case this last loss would seemingly be bad luck on top of something that could have been treated.
That said, neither of our bodies straightened out immediately following our later losses so... maybe embrace that might be the case again and stick to plan A of resting up, gentle exercise, taking the vits, getting in a good place...
I'm not bloody helping with this flip/flop back and forth, am I? to you though my lovely. Maybe the 'answer' is time? It'll become clearer with a little more time.
midget That's some good lickin'! Fanks! 
(this licking business totally makes me smile for reals - it's so...pythonesque and appeals to my silly side!)
jaffa Thanks for the advice - I slept with a pillow between my legs last night which although oddly distracting seems to have had a positive effect - oh, it's still 'there' but I'm not hobbling like an old granny going 'ow, ow, ow' this morning so yay for that!
Seriously, yay, though... I clicked a link on the mumsnet email last week to enter a 'competition' to be in a video promoting New Looks new maternity range... and they just called me to say I'd 'won'! So, on Thursday morning (horribly early for me - 7.30am) a car will collect me and off I go! I don't suppose hobbling will be a good look (talk about sods fricking law - been fine up until yesterday!). So, next few days I'm gonna rest the heck up and take painkillers come thursday if it comes to it!
