Untenured TTC??

I am going to be 30 and have been married 5 years. My husband and I always wanted for me to be tenured before we started a family, but teaching jobs in my area are very hard to get. For the past few years, I have done leave replacements and had a part time position last year. I recently landed my dream probationary position that started this past September. This is my first tenure track year and won’t be tenured for another 4. Do I continue to wait or is it possible to get pregnant for next year and have the baby in the spring (second year)? I have no idea who to ask and I’m not sure what to do. I’m also working myself to the bone this year and I’m on every committee, club, event at the school and already did over 78 pd hours this year. How do I make my decision? Was anyone else untenured?
