redstrawberry sorry to hear about your job problems - I've been through that kind of switch myself! Don't want to stir but is there any way you can go back to your old workplace? Or will sticking it out at your new place until you go on maternity leave be good career-wise (and then move on to somewhere else when you want to go back to work, if that's possibly timing/financially-wise?)?
jobcar You've got DH on board - that's the biggest obstacle over! Soon you'll have the wedding planning occupying your every thought... so probably good to wait until AFTER the big day to TTC! And it means that you have an extra incentive NOT to blow all your loot on the wedding (which, from experience, is an easy thing to do)! :)
Ok some updates for my situation... we are going to start TTC in December!!! How do these schedule changes keep happening you may ask?? I'm worse than Ryanair!! Well... mostly I keep getting over babycracked out and plead my case to DH. To get to starting TTC next month though, have had to make the following concessions for the month of December:
- I do ALL of household chores next month
- change kitty litter every day (wearing gloves and maybe a mask for baby-safety reasons - and as soon as I do get pg it is back to being his chore!)
- I make him his favourite dessert every weekend until the end of the year (starting this weekend)
- He gets full naming rights on DC#1. In fairness he'd probably get the final decision about a baby name anyway as he's much more fussy about those kind of things than me.
Ladies, what have I done?!?!? I've signed myself up for a whole lot of work in December! But I'm ECSTATIC and I think it's worth it (ask me again in a few weeks' time...)! I think I made a good deal.... 
Booked flights to Australia and NZ in late March and I have every appendage crossed tightly that I will have exciting news for friends and family by then.... come on CBFM, work your magic!!
