I really don't understand....I'm 4days late, nauseated, tender boobs.....and a BFN!!! I'm only ever 1-2days late....the only time I'm ever as late as what I am is due to pregnancy!! I'm not stressed, I'm not thinking about it every minute of the day....I just don't know! I'd there still hope or should I just cut my losses for this month?!? Could really use some advice please!!
