Scared to have a baby! No judgemental comments pls

I wanna have a baby, I really do.Me and my husband would love to grow our family,but am scared.

I have read stuff and seen in perosn, about ppl having C section and their body never coming back to the same way it was, the pain.

Am scared about how life will be after a baby, would the sex change? I heard parents become very tired after a baby,and hardly have any time for intimacy which eventually affects the marriage.

I sometimes fear I might regret having a baby.I wanna have a baby and be the person i wanna be,and have a happy fun life too..
