Currently pregnant and having doubts

I’m 22 weeks pregnant and I’m currently 24 years old and it’s been hitting me that i think I’m not ready for a baby. I was fine at first and excited but now i feel like reality is hitting me and the weeks are coming closer . I feel like a bad person because I’m not sure if i want to have my baby . Is this a normal feeling that moms get ? This is my first baby and i feel so bad for feelings like this because I’ve always wanted a baby . My pregnancy had been such a great pregnancy i just don’t know why I’m feeling like this . Mommies can you help a girl out ? 🥲
