Will I change my mind about having kids in the future?

I (F27) have never had any desire to have kids and to be honest pregnancy scares me so much. Having a family is just not something I look forward to.

I always hear people say that I will change my mind in my 30s but I’m doubtful. I’m currently in a relationship with a man that really wants to have a family in the future and it makes me a little anxious. Did any of you change your mind when turning 30? I want to hear stories from those of you that did not want or wanted and changed your mind in your 30s.
