Postpartum body.

Okay so no judgement please , but I'm 36 weeks pregnant. I weighed 104 pounds by the time my son was 5 months old.. But this time I weighed 123 pounds when I got pregnant (thanks depo) anyways I had been trying to lose the weight when I conceived.. I now weigh almost 150 pounds which is fine.. But I'm worried about what I'm gonna look like after she comes out. I'm scared that my husband is gonna be disgusted by me , and I'm also gonna breastfeed but I'm worried I'll become so obsessed with weight loss that I won't eat enough to breastfeed. Is this normal to feel like this ?
