Just wondering if it’s normal

About a year or so I had an abortion because I wasn’t in a relationship the guy and I knew he was a dead beat because he didn’t take care of his first child and he abused his bm and I was still in college and had a lot on my plate. Through out it he didn’t believe he was the father and didn’t want to help nor didn’t want me to abort it. So I had to do it by myself with no help of anyone other than someone who was my best friend at the time. Until this day I sometimes tear up about it but I just wonder if that’s normal. Also I really was like a week pregnant so nothing major was going on and when I decided to abort the pill sounded like the best thing to do. While that was going on I was wondering if I could see anything but I didn’t because it was too early. So I’m just wondering if that’s normal to think about it some times or something. Please share your thoughts!!!
