Confused?

Im 14w5d and some days I feel huge and I feel like I look 6 months pregnant, and then their are other days (like today) where I feel as skinny as I was before I even got pregnant. I don't even feel pregnant anymore. I miscarried last year at 12 weeks and the baby stopped growing at 6. I'm not having any miscarriage symptoms, I just feel extremely normal today. Is this normal at all? Please don't tell me I'm alone in this. Although I still crave taco bell everyday as always lol
