Are these red flags in postpartum ?

I’m currently 3 months postpartum and did struggle with postpartum emotions (but was never diagnosed with anything). Since then, I have noticed 5 things.

1 - i have an odd bond with my son. Like I love him but I don’t feel connected to him either. I feel more connected to the kids at my work (a daycare) than I do him and I feel guilty.

2- I really want to be pregnant again. I miss it SO much. Looking at old pics really breaks my heart.

3 - I’m having a really hard time with noticing how much he’s growing even just now. It makes me depressed that he’s even out of me, let alone growing.

4 (and this one is weirdest to me) - I just keep getting this feeling that my life is boring. I notice I’m spending a lot of money on things I don’t need to try to make myself happy

5 - My weight is fluctuating and I feel fat. (5ft5ish and weigh 139). I have thought about starving myself
