should I put tcc on hold

Lisa
Hi 
My husband and I have been tcc since we got married 4 months ago.  However I now have an opportunity to change careers and am through to the final stage of being selected for the ambulance service.  We want a family but this change of career is a fantastic opportunity and I'm not particularly happy in the job I am in now.  Has anyone else decided to put things on hold or just continued trying.  Thanks for your help xx
