Well TWW is up

Well my TWW is up kinda scared to test because I don't wanna get my hopes up my fiancé wants to be a dad so bad he is the only Child without a baby.. His older brother has 3 two boys and one girl, his baby sister thats 22 is pregnant with a baby boy.. He feels so down because we lost our first one when his sister found out she was and that was about 8 months ago... So. Should I wait to test or go ahead.. BTW my fiancé works in the Oil field and won't be home til Saturday..
