Welcome lady. Congratulations on first bean! I am sorry about the mc. It is awful isnt it? But it sounds like you are doing well if still sick etc. Those hormones are bitches but at least keep us in the picture!
I will also add my story to the working / SAHM topic, and it is similar to tiddleys. DH and I had good jobs, good money, prospects etc when we got pg with dc1. It was always assumed I would go back to work and we found an excellent nursery, part of a good private school we intended to send children to long term. And then I had ds1 and I was addicted to him!
I remember walking around the Downs (a stunning open parkland in Bristol) on a frosty November morning and tears streaming down my face at the thought of leaving him. It was about 6 weeks off me going back to work. Told DH and he said, well we won't have as much spare cash, but we can easily manage it, and I phoned my boss that evening to tell him I wasn't coming back!
Never regretted it. I am a bit conscious sometimes of being the living epitome of the type of person that gets short shrift on MN, ie Waitrose shopping, White Stuff wearing, SAHM doing the school run and coffee mornings, but this won't be forever, it is a phase I am enjoying and I know at some point I will go back to work, and hopefully do something I enjoy!
So, my take on it is, wait to meet your baby and then see how you feel. The choices made before and after the birth sometimes can seem worlds apart!
