Having read your update, I felt I needed to add this: your desire to have a baby to cement your marriage is not fair either to your husband nor to the baby. What a burden for him, he has to be cute, healthy, fulfilling and a bandaide for a troubled marriage. A baby is often the straw that breaks the marriage. I would tell your husband that you are going to counseling to discover why you are so unhappy in your marriage. he can come or he can resist, but you will know what your issue is and then decide where to put your efforts.
Your thinking re; cause and effect is off here sort of like the 55 yr old man who goes out and gets himself a trophy wife. He assumes that will make him happy. Both the baby and the wife are efforts to turn back the clock. I wish you well in your efforts to find satisfying life.

I think what you are fearing is a lack of identity and purpose. "If I am no longer needed by a baby, what will I do?" Most "accidents" happen when the baby goes to kindergarten. That happened with my own mother and she had her 5th at 40. He is fine, but it was a real strain on our family.
I remember those same feelings and having dreams of having gotten pregnant when my baby went off to kindergarten. So, assuming that you are suffering from the same angst, here are some ideas, in no particular order:
1. Go get tested for a career at the community college, find out who you realy are.
And start making plans for your post stay at home M. role.
2. Become a foster M.. You can tell CPS that you will only take babies, only school age, whatever you want. You will receive a small amount of compensation and kid's medical insurance is taken care of.
3. Decide how the world needs fixing and set about fixing it. Volunteer to advocate for abused children (CASA) or be a mentor in the shcols. Advocate for the mentally ill, work in your church's food pantry.
Recognize that this is your year to morph into a new stage. It may be almost as painful as adolescence without the acne. Fortunately, you already have your mate picked out so that difficulty is solved. Do not make this about him, it is about you. Kiss, make up and try to figure out what comes next.
Good luck.
