Is this postpartum depression?

So I had my first baby 5 days ago and I am so emotional now. I miss my husband soooo much even though he’s been with me most of the time. I just feel like I haven’t talked to him. I’m even crying typing this thinking about how much I miss him and he’s sitting 4 feet away from me right now. I guess bc the last few days has been about the baby. We didn’t get much sleep. But I miss him. I miss just the two of us doing things together. I miss him giving me massages every night before bed . I miss us picking out a movie together on Netflix to go to bed to every night. Is this the beginning of postpartum depression everyone has been wanting me about? What was your postpartum depression like ?
