I feel as a woman and working, when we get pregnant can greatly affect our careers. I want to eventually become a nurse but with starting a family I think I will be done with school in about 4 years realistically.
I've been at this more than 2 years now, and I was off to a late start because of my career. I understand where you are coming from completely, because I also started out trying to figure out when TTC and my career would fit together the best.
Six years ago, I started a new (demanding) job and thought I needed time to prove myself before I could start TTC. Then five years ago I was ready to start TTC but it became almost impossible because I was traveling 2 hours each way to my work and flying out for a work trip almost every month. I was either too tired to BD, or my DH and I just weren't in the same place at the same time whenever I was in my fertile window.
It wasn't working for me, so finally 3 years ago I changed jobs within the company to be closer to home and not travel. We started TTC on our own but within six months we knew we needed assistance...
What I have learned when it comes to career, is that if TTC is a priority it needs to fit in with your job by having a more flexible schedule, and/or support from management.
Sometimes that's realistic and sometimes it's not. This year I had a real breakthrough when I told my current manager I'd had a loss from IVF. He encouraged me to keep trying and to take the time I need for doctor appointments.
With your new schedule, you will have an extra day to take care of yourself which is great, and time to get used to your new schedule which you need. My best friend will be graduating in June and become a nurse and she is a single mom to a 7 year old girl. She didn't plan to get pregnant and then to start school, but it just worked out that way, and she's getting the offers she wants. I really hope the best for you and have my fingers crossed that you'll get your BFP sooner than later. Everything works out when it's supposed to.
