I would listen to your gut OP. You shouldn't be TTC unless you are confident you feel ready, and ARE ready.
The girls trips don't have to stop, if you're in a good relationship/partnership with someone. You can still do them when pregnant, and when the baby is here after the first few months you can easily still go off and do stuff, as can your husband, with the other staying home with the baby. Don't fall into the trap of assuming once the baby arrives you'll be tied to them for five years solid, that's how a lot of women end up with no identify beyond 'mum', and sighing about 'having to' stay home when in reality they've chosen to limit themselves from day one for various reasons.
You are young enough to still have time to enjoy your life for another couple years then try, so if there's any doubt whatsoever I really would say don't start trying until you've worked through that. Everything really will change.
I will be honest, your post reads like someone who knows on paper they 'should' be having a child soon (married, age, social pressure) but they don't actually want one themselves and would prefer not to. Parenting is hard, and I think there's a real chance of you resenting it if you plough on now and don't listen to what your heart and your gut are yelling at you.
By the time we started trying I'd wanted a baby for several years, waited until everything was in order, and then tried at 31. I was so ready, I was absolutely DESPERATE to get pregnant and have a baby. I can't emphasise how badly I wanted it to happen. I felt like I needed to get pregnant and have a baby immediately. The thought of actually being pregnant then becoming a parent felt so unrealistic because it felt like winning the lottery. I am really grateful we got pregnant and it panned out and I can truthfully say now, 6yr later, I am still just bowled over by the fact I get to do this and raise this human, I will never take it for granted. It's magical. I know other parents who deeply regret ever having had a child, because it wasn't for them but by the time they realised that it was too late. You have the gift of time right now and of being able to make the right decision without rushing into something disastrous.
And it's worth saying, when you TTC you're opening up to any outcome. You could have triplets. You could have a child with serious health issues who needs lifelong round the clock care. One of you may have to give up work. You could be left with a serious injury and lifelong pain. You just can't know, it's a coin toss. So when you start trying you really do need to be ready to accept whatever comes and feel that it's worth it.
