It depends on your age. If you are not over 18 years old, you need a guardian's signature. If you are not over this age now, if you tell your parents, they will probably beat you to death. But if you don't handle this pregnancy well at such a young age, a random medical abortion or artificial abortion may cause permanent damage to you, or even make you infertile for life. Now you can be said to be making the world unresponsive and the earth not working. You'd better discuss it with your family.
