I'm pregnant at 15 and my mom is pushing for abortion
That sounds rough. How do you feel about your mother trying to get you to abort?
I'm angry and am thinking of pretending to lose the baby.
Instead of lying, you should tell your mother that having an abortion is up to the person who's pregnant. There are other options you can always take.
Fuck that sounds hard and I feel like just taking pills like other girls.
You shouldn't take anything that may harm your child if your intention is to keep it. For your safety and your babys, tell your parents what you actually want to do. That way they can know your true feelings before making any important decisions.
