This thread seems really old but hopefully someone will see this and respond. I am 45 next Thursday with DD's 21, 19, 7 and 4 and thought we were done. Just took a test yesterday and it was positive. I am in total shock, scared, I am married but my husband works abroad, and we thought we were finished. I have always avoided BD around day 9-14 just in case but this time clearly not. I am not happy right now, at all I just don't see this as a good thing :(. I am happy with the four we have and feel too old to do this again. Any advice from older mum's would be welcome. Really just in shock still.
