I have a bit of the opposite problem. I had a good career, had my DD and then went back to my job after a 7 month maternity leave. When I went back, I was working crazy long hours, and started really resented my job and realised that I wanted to change careers (I worked at an advertising agency and decided I wanted to go 'client-side' because I think there is more longevity for my career there). So in a fit of frustration (and agreement with my DH), I resigned.
I have been looking for a job since (3 months) and I may be about to land a good job (fingers crossed) with more money but my other dilemma is that I REALLY want another baby.
We did try for another one a little when I went back to work but we didn't really make it a priority (we were both too tired). But now I'm thinking I am 36 years old and in the big picture, family is important, not a job, and I can't delay number 2 for too long because I'm not getting any younger.
However if we just get pregnant now (if we are lucky) I will be out of the workforce for 2 years (because no one will hire a pregnant girl and then I would be on unpaid maternity leave because I was not working before).
What has added to the baby pressure (and I knew I would feel this way) but 2 of the girls in my NCT group are pregnant as are a few of my friends so I am super jealous and super broody. 
I wish I could turn back the clock, not resigned, got pregnant, took mat leave and then looked for a new job after baby 2.
I know nothing can be planned that way but now I just feel stuck that once I am in the new job, I will have to be there for some time so I don't pull a "Natasha Kaplinsky" and announce I am pregnant shortly after joining.
Ug. I have a constant pit in my stomach because I yearn to be pregnant again but know that I now have to sort the job out first.
Am I blowing this out of porportion? I just feel like I made a life mistake.
Anyway, my advice to others is to sit down rationally with your partner and make a pros/cons list with timescales before making any big decisions.
