I can not stop feeling very broody help?

You sound very sensible to me. Do the right thing, wait until you are absolutely positive its what YOU want, and don't be 'left holding the baby' if you know what I mean. Us women DO get broody sometimes, just part of your motherly instinct I think. I guess you will know when you are ready, but I does not seem to be right now cos you are having doubts. SO WAIT. Good Luck sweetie.
