Women who regret having children, why?

Edit: I would like to mention a couple things. I do not have children and I know I do not want children. I am asking this question to all women who have kids and feel this way (not specifically to women who have kids but didn't want kids and ended up having them anyways). I feel this is a topic worth discussing and the answers here are all valid and deserve to be heard. Posting things like "if you didn't want kids why would you have them" or "if you regret having kids, you are selfish" is really not adding anything to the discussion here. Thanks folks.
