I can't give advice, but was in a similar situation so I'll give my experience.
I have always wanted to have kids. As soon as we were in a position to practically start a family (had bought house and financially secure) then I was keen to start trying. I was just approaching 30 and my biological clock was screaming 'baby, baby baby'.
I knew my partner was not as keen as I was but he agreed to stop using protection. I told him we didn't know how long things would take. My mum had a hard time trying to conceive her kids and that was what I was expecting.
A few weeks later I got a positive pregnancy test and life changed forever. My partner was excited and he embraced the experience but I've always been aware it was a bit of a rollercoaster for him.
We decided to get married (shotgun wedding when I was 16 weeks pregnant) and had a very busy 9 months sorting this and preparing for baby.
On reflection I'm sad I missed out on having more grown up time with my husband before the hard graft of parenting began.... Gone on lovely holidays and weekends away. I know my husband has felt this way too.
I have talked with my husband about these 'regrets' and I've made peace with them.
Ultimately having kids was the most important thing to me and I count my blessings to have conceived 2 beautiful children with the man I love with relative ease. He doesn't hold any bad feelings and he's a wonderful father.
Luckily having kids has drawn us together and we are stronger as a couple.
It's hard to make a rational decision when all your brain is screaming out for is baby.
I'm such a pessimist, I'd expected to be going to the infertility clinic in 12months time, not getting pregnant straight away.
I wish I could have trusted things would be OK, maybe I would have made different decisions if I'd been more positive in my outlook
Anyway, no regrets now, just enjoying my beautiful children and will look forward to living it up when they are more grown up.
Good luck making your decision and with whatever path you take.
