Most women are guilted over having abortions. That does not mean that they felt the same way about it personally. My cousin got pregnant a few months ago because she switched birth control and it failed and she was all for having an abortion. Her and her husband had two kids, didn't want another and the hospital wouldn't tie her tubes cause she was 'young' (30 yo). She was all for it. Until her family started to get to her and the more time passed, the less sure she was. She ended up having the baby. I have another cousin who had an abortion and when I asked her about it she was like
I just walked in there, got it done and dipped. She had support. Her BF was for it too. She doesn't think about it. Nobody was telling her what she did was wrong, because it wasn't. In my opinion, the unhappiness, if it comes at all, comes more from societal views than the actual abortions.
Research seems to agree with me.
The truth remains that most substantive studies in the last 30 years have found abortion to be a relatively benign procedure in terms of emotional effect --- except when pre-abortional emotion problems exist or when a wanted pregnancy is terminated, such as after diagnostic genetic testing.
