What’s wrong with me?

Back around the end of December I found out I was pregnant. I found out pretty early so I was a head of the situation. I got an abortion at the end of January and I still haven’t seen my period since. Key things to point out, I’m still a teenager so I did this without the knowledge of adults, I found out on a stick, I never went to the hospital or saw a doctor, I had the abortion pills shipped to me, I went through completely alone, still won’t tell my parents
