Was in the same situation as you: 30, happily married, surprise pregnancy. I also briefly comtemplated termination, because I was concerned about impact on my career, ability to travel, my freedom etc. Also I think because I am a planner, I like to plan things and this felt like something I hadn't had control over, so that's why my mind went initially to termination. Not sure if that makes sense or not.
I didn't get as far as booking the termination. It was something I thought about and then dismissed the idea. I had my beautiful son 8 months later. Becoming a mum was the best thing I've ever done, my beautiful boy is amazing.
My husband is a really supportive husband and father. Although it's not a 50:50 split of childcare, that's not because he shirks the responsibility, it's because I like being a mum too much to give him more responsibility, if that makes sense.
I returned to work after 14 months of maternity leave. 4 months after that I was promoted into a new role. So although I did put my career on hold for those 14 months or so, it did recover afterwards. Also having a supportive husband who's a hands-on dad enables me to put some focus on my career.
Regarding travel, Covid broke out when my son was 7 months old, so I've literally missed out on absolutely nothing. Regarding social life, ditto. Covid = very limited opportunity to go to restaurants, go out with friends etc.
Only you know your career situation, your employer, your husband, your life etc. In my case it worked out but that was down to my circumstances.
Whatever you decide, I wish you lots of love and happiness
