I'm 14 and pregant. What do I do?

I'm 14 and pregant.I'm a v*rgin, I sware! My parents and two sisters know and I know they ain't so proud. Should I keep the baby or not? If I do, I know my family and friends will be so helpful, but I have a job, LOTS of homeowork, personal time, school, and then adding taking care of a newborn baby is not helpful. I'm really scared and nervous. I really don't wanna be a teen mom I wanted to have a baby in mid 20's NOT 14! Someone please tell me what to do, I don't wanna hear listen to your heart because trust me I been thinking alot. Any teen moms that wanna give me advice? ThaNkS.
