I have the ache. I'm trying my best to move past it, but I don't know if or when I will.
I have three kids 11, 8, 4. I also have one angel in heaven (my 4th pregnancy). I think having that miscarriage made the ache worse. I was able to dream for 8 weeks of having 4 kids, and had everything all planned out in my head. It was hard to switch gears afterwards and I still feel like there is a missing piece. My husband does not want to have another. The 4th was a surprise pregnancy and I think he was half relieved when we lost it. He is happy to be past the baby stage and moving on with raising our kids. We are 38, and I was diagnosed with 2 health conditions this summer which would most likely make pregnancy very risky.
So, to answer your question, the matter has been decided for me by my husband, and my health. If it were completely up to me and I had no health concerns, I'd have another....maybe even more.
Best wishes to you!
