Postpartum Depression?

Hey everyone! I just a my precious baby girl last Monday. I’ve never had Postpartum Depression before so, I’m not sure if that’s what I’m feeling or if I’m just depressed. Here the last two days, I have just been feeling sad. I will sit here and just cry. I still take care of my baby girl, that’s no issue and I’m not having suicidal thoughts. I keep feeling sad that I’m not longer pregnant. I don’t know if it’s because she’s my last baby I’ll ever have or what it is. I just can’t shake the feeling and I feel like I’m going crazy. 😔
