New to group need some positive words.

My husband and I are ttc and I took a pregnancy test today and it was a bfn. We're both kind of bummed about it. We already have 3 beautiful children and this one when and if it happens will be our last I'm sorry if anyone feels like I should be happy with the 3 we have (All of which I love more than life itself and have been told to not be bummed because I have 3 kids already and so on) we just want 1 more so badly and to get a negative was rough. I'm sorry to whine.
