Feeling sad for certain mamas to be..

Because I read about one lady who has been trying to get pregnant for 5 years now with no luck... And just now, read that another lady has only been trying for 1 month and got pregnant, but referred to herself as having waited "so long!"
I am so, so happy for any female that is wanting to get pregnant and does, but feeling very sad for the mamas that haven't had their chance yet. 
And congratulations to those that have used theirs.
