How long?

How long did it take you to conceive? I have been blessed with one amazing daughter but we really want another child this is month 13 of ttc and it’s killing me! I’m getting to the point of giving up 🥺 it’s just not in my nature to give up on something that I want so bad but every month I get my period or that negative test really gets to me 🥺 it feels like everyone and their dog is pregnant or just given birth and every one upsets me that little bit more because I think why not me?? Am I not good enough?? Maybe I’m not good enough mom to have another?? I don’t know it’s just really getting to me why is it not happening 😔
