well i wish i could tell you that you could change it but you cant. You need to really think about it and what you want. trust me i know your not ready becuse i wasnt ! im 17 and just had an abortion i made the biggest mistake in my life by getting rid of someone innocent and small... and it was extremely hard telling my mom! so just do the right thing follow your heart. i wish you the best girly . just dont make a mistake because your scared im sure it will be worth it when you have that tiny precious child in your arms!
good luck!
