PPD fear

Did anyone else worry they were going to have post pardom depression? I had my daughter 3.5 years ago and through my whole pregnancy, I talked to my belly, and I rubbed it, and I just couldn't wait for her to be here.
I've had two miscarriages and now I'm 32+4 with a boy. I just don't feel the same way. I don't get as excited shopping for stuff, and I can't wait to be done with pregnancy, but I'm not as ready to have a second baby.
I'm worried I will have PPD and not be able to tell my fiancé.
Anyone else think they were going to have it?
