Wow lots to catch up on.
mike RESULT! So lovely to hear you've had a good 20 week scan and healthy baby in there, I'm so thrilled for you. And congratulations on a little girl 
I guess you can slowly start musing names now. Slightly dreading that bit again, it was bloody difficult! Slightly hankering after a Felix or a Cleo but I think DH might complain they are cat names.
truly and pasta fab scan news too
truly that's a bugger they didn't get the measurement. Could you ask them to do an internal scan for that? I had to have an internal once at 13 weeks purely because the baby was so low down they couldn't see through my pelvis very easily. They get a much clearer picture. Otherwise, the options I believe are the quadruple test (after 14 weeks I think?) which is just bloods, go private for a NIPT test such as Harmony (anytime from 10 weeks) or cvs/amnio, but amnio is after 16 weeks and obv those are both invasive tests and I don't know if they do them if initial bloods are not concerning? Someone else might know more here.
Maybe post in the antenatal choices section, there's lots of very knowledgable people there who could explain options properly.
whatser I hope you're ok after yesterday 
mimi I hope booking went well and you've got a nice midwife. No advice tbh on approaching significant scary points - it is really hard and it's just a case of head down and plough slowly through the days, have a few freak outs and big cries or shorttempered grumpiness and don't expect too much of yourself. It does feel a bit easier afterwards, - for a while anyway!
((lynsey)) this is hard work psychologically. You are doing really well. I know and understand the anxiety oh so well. I'm perhaps not the best person to reassure you because of the circumstances of my first loss, but I know in my subsequent pregnancy with DD I completely lost the plot over germs. I refused to eat a thing that grew in ours or anyone elses garden (cats) so gave away kilos of homegrown strawberries that I couldn't eat, I disinfected the entire kitchen multiple times a day, I refused to touch the cats full stop, I set the dishwasher up to 70C, you get the picture. For me there was so cure apart from giving birth to a live child so I don't really have any tips, but much empathy If it carries on past your scan talk to your MW/GP they might consider CBT for anxiety or meds or something. I believe there is often a perinatal mental health team too, might be worth enquiring, they must see super anxious women all the time and have ways of helping.
11+6 today and feel sick everytime I look at the calendar and think, shit, Tuesday is the scan. Oh god. So bloody tired, I went to bed at 6.45pm last night. I think I have worked out though that it's my antisickness meds acting as a near sedative. I managed without them on Thurs and was tired but not comatose, it was much better. The flipside of course is that I felt really sick through the evening so I wussed out, had a tablet yesterday and was a dozy useless person afterwards.
