thanks for the welcome everyone

Duchess: no all my tests were normal so i don't have any genetic issues that might be causing a problem, I think it is basically down to my age although i do have quite a few endocrine problems (had half my thyroid removed, previous pituitary tumour etc).
I hope you had a nice day with your DD, those questions about the baby are so hard to answer I'm sure

Melster: you sound really stressed ! I'm starting to wonder how I'm going to cope getting 2 children ready for school next year and organise a baby too, i guess it will all fall into place, at least i hope so !

me4ever: great news your ob appointment went well, hopefully you can relax a bit now
