You really need to speak to someone about your options, If your having doubts one minute and looking at baby furniture the next then don't rush into an abortion. Weigh up the pros and cons to each side and above all put yourself and your 6 year old first. Look at your options if you decide to keep this baby but also be prepared for how you'd feel if you went through with an abortion you weren't sure about, it is not always the easy way out. Hope this helps, good luck!
have you ever thought about adoption?? I think that'd be a good way to go if you can't handle having the baby. I'm adopted myself and I thank my birth mom every day of my life for the sacrifice she gave.
