3 months and a little sad

My baby turns 3 months tomorrow and everywhere I turn something reminds me of being pregnant and I love her more than anything but I really miss being pregnant and having her in my belly. To the point of tears sometimes. I don’t know what it is. I loved the feeling and now it’s gone and I’m still sad. My hormones were crazy after giving birth and I was crying all the time but that has totally gone away. Now it might just be once a week when I’m at work or something. Is it normal to miss the baby in your belly? Idk what it is
