Need advice!

Okay. So here it goes. My husband and I already have a 7 month daughter and we recently found out that we were expecting another. (Haven't gone to the doctor yet btw) as of right now we are not in the best position to have another since we are renting a couple rooms from a friend. I just don't know what to do. With us not having our own place anymore we don't want to keep this little one but I don't think I could go through with abortion or adoption. Thoughts?
