Nighttime sadness

I had my baby 5 days ago, and I’ve been feeling so sad ( of course I’m so in love with him)

I think because I had such an easy pregnancy, like I enjoyed every step of it. I miss my big belly and feeling his kicks.. I loved loved being pregnant and I just miss it so much. Now when I look at my empty belly I breakdown and cry. Or I just cry over nothing there’s really no reason sometimes.

Is this normal? Is it just hormones ?

I feel like I have no one to talk to about it

This is my first baby I’m 25 years old and my husband has been very supportive but I know he doesn’t fully understand
