Too late to say I am sorry... But hey congratulations!!!! It is the best decision that you are going to keep the baby.
Motherhood is full of obstacles that you will definitely be able to over come. As for your 'partner' there will be a moment where he will regret that he made the biggest mistakes and that is take responsibility what you both have done.
Being a young mom, at first you prolly won't enjoy it. But think of the positives... in 10 years time you will be 28years and you will have a daughter or son who is all grown up and by your side as your best friend.
Right now every moment/ minute when you start to feel upset, start looking at baby appliances and start to think of the positive. Think about your baby inside you that needs all the nourishment inside you until you give birth.
You have to make positive sacrifices now.... for your baby :D
All the best..... come and visit my family site
