how many people regret having kids?

how many people regret having kids? Im glad i dont hear that often that someone regrets having kids but I wonder how many people regret it,since there is such a negative reputation about it I dont know how many people realize they dont want kids or never wanted them. there is just too much pressure to have kids even if you do not want to have any. I hope with time there will be no pressure to have them. my mom said she wanted kids until she had me then she realized she does not want children. she got told it will all be different when you have a child you will want it. like thats always the case. luckily she does try to be a good parent sometimes.
