I have a different perspective again.
I'm 34 and have been trying for a baby for years. Tick all the boxes; happily married, financially secure, job with full maternity benefits etc. Our next step was IVF. There's no reason for us being unable to conceive- unexplained fertility. We tried everything. Sperm Meets Eggs Plan, special diets, low-level intervention: everything up to IVF stage basically.
A few months ago, it got too much for me and I needed a break. I took 2 months of not temping or tracking and just parked it. I even avoided sex at what I knew would be peak times, just because I didn't want the "what if" at the back of my head.
A few weeks in, I was feeling better. I wasn't consumed with jealously eyeing up bumps, or dreading getting period symptoms.
Then I started thinking about what having a baby meant to me. I actually wrote it out as a pro/con list, and came to a few conclusions:
I didn't feel like I was missing out by not having children
I didn't see becoming parents as having a guaranteed positive impact on our marriage
I wasn't jealous of people with babies, I was upset that my body wasn't doing what I told it
I couldn't see an area of my existing life that would be improved by having a child
We have zero family support around me and would have to miss out on a lot of the things I/we love doing, by virtue of the fact that I/we would need childcare constantly
Then I started speaking to people I knew who had kids. Most were somewhere between "it's great" and "it's ok" but then I spoke to my two sisters. One has a child with an incredibly severe physical disability. We adore her but my sister and BIL's lives changed the day she was born. They're totally dedicated to her, but can't deny that their days are consumed with hospital appoints, and worry.
My other sister has children and again she loves them but her take on it is that, if she was to go back in time, she'd have stayed childfree, for a multitude of reasons. She's confessed that, while she loves them, she sees no advantages in having had them and went on to say that, in my position, the last thing she'd do is have children.
My husband and I are still discussing our next steps.
At the end of the day, there's no magic answer. I understand the power of broodiness and that sick feeling of seeing a bump and not being able to have one of your own. That said, if there's a niggle of a doubt in your mind, you really do need to treat it as you would any other big life decision- sit down, plan it out, look at pros and cons, plan finances, plan logistics, and mitigate for what happens when things don't go to plan.
