I'm sorry to hear about your miscarriage. Some of the advice on here is good though.
You have lots of people giving you advice based on their own experiences, and whilst that will not completely translate to your situation, they are trying to tell you things that are unanimous for pretty much everyone.
I had DS when I was 28. I still hadn't travelled nor had I gone out alot with DP. I wanted to go to festivals. I still do. I wanted to go on holiday with DP alot more. Do a few more hobbies etc. My singing has gone completely out the window and I can't even practice for half an hour an hour constant interruptions.
Don't get me wrong. DS has been the most amazing and precious addition to our lives. It's so much richer having him in it. However...
I couldn't workout for the first year. DS was very clingy and would cry whenever I went out of the room for more than 10 minutes so I couldn't concentrate.
He still does not sleep the night through at 18 months. I'm permanently exhausted. You know that feeling when you're a bit run down? It's like that constantly even if you have a good night sleep.
For the first year, I slept next to him and went to bed at 8pm, at the same time as him. So no social life really, no time with DP in the evenings.
He also had colic which made going out, just for a coffee, very stressful and unappealing. It's was emotionally draining to cope with. That was something we couldn't have predicted would happen.
I have no doubt you'd cope with a baby. You'd love it actually, I reckon (though I know not everyone enjoys it). My point is everything is so much harder when you do have one. There is no reason to rush this when you can have a few, or a couple of care free years where you can go to the toilet in peace, eat a hot meal and have a hot cup of tea (you will never appreciate these simple things more when you have one 😂).
It is ultimately your decision but why ignore what so many are saying? Why rush? Have fun a little bit more, live life a bit more and make some more memories 🤩
