When I met my now DH we knew time was ticking on for us fertility wise so started ttc quite early on, once we were sure about each other and knew it was for keeps.
It took a while and meanwhile we started planning a wedding. I remember tying myself in knots thinking well if I get pregnant then, I’ll be x months old pregnant at the wedding or I’ll have a newborn etc etc. Although by this point we were beginning to accept it wasn’t going to happen full stop.
By some miracle we managed to get / stay pregnant and it couldn’t have been worse timing in some ways, I was about 9 weeks pregnant, bloated, sick, couldn’t drink, ridiculously anxious and not particularly able to relax and enjoy the build up/ day/ honeymoon.
But none of it mattered a jot, we had a fabulous day and now have an amazing DD and I wouldn’t change any of it. It’s actually quite nice getting married when you are pregnant, despite all I said above it actually felt extra special. And I’m so glad we have the legal side of things taken care of, particularly as I took extended mat leave and have only gone back part time for the first few years anyway.
Also I know loads of people who thought they’d take care of the wedding at some point once the baby was born and it hasn’t happened years later.
In your shoes I’d absolutely go ahead and get married. But then I was never one for ‘the time has to be exactly right’ either - I was with one of those for 12 years in the past, the time was apparently eventually right and we got engaged but never actually made it to the wedding, he was shagging someone else before we got that far 🙄 So that’s definitely coloured my view - these days I really believe if you want to be married (either/ both of you) then you go ahead and do it, all the faffing about perfect timing is just a distraction.
