Not wanting the baby anymore

Im 30 weeks so far and all the changes i had to do since i found out i was pregnant plus the things i will have to change when baby is born are really pushing me down. Which is why i think i feel this way.

I can't shake the feeling that i should have been more careful and that i want things back to the way they were. I feel aweful, cause i do love the baby and if i could choose again i would not change how things are.

I just feel so anxious that my life is so different now, and i get stress cause i don't feel pretty anymore, i'm always tired and unconfortable, and i can't properly sleep. It's not all the time that i feel this way, it started recently but it's getting worse as time passes by.

This is not fair with my baby, how can i change how i'm feeling? I don't want him to not feel love, i do love him and i do want him, it's just so hard to get use to this changes
