Is this postpartum depression? 😞

I just had my first child late Friday night and already i am noticing I just don’t feel the way I thought I would feel. Everyone kept telling me about this feeling you’d have when you see them for the first time and I just don’t feel like that happened for me. I don’t feel like I’m attached to him at all and i don’t feel like he’s MY child and I feel like the worst person in the world for even having these thoughts. I have never been the most sentimental person but I thought i would at least feel more attached and emotional about my own child but so far I don’t. My husband has been talking to him and playing with him and I just don’t have any desire to do that. We planned this pregnancy and I was so excited for him to finally get here so why am I feeling like this?
