I don’t feel pregnant.. is this normal?

Hey ladies! So I had a miscarriage at 8 weeks in May.. DH & I started TTC in August & we recently got a BFP, I don’t know how far a long I am yet, I’m getting an ultrasound at the end of this month.. but I don’t feel pregnant.. is this normal? Last time I was pregnant I felt terrible, I had mood swings, was always mad & stressed out, really tired.. I remember feeling a lot of cramping, no morning sickness, no nausea, and lots of cravings. This time around, I have headaches - is that a pregnancy symptom lol? I find myself taking naps, just like last time.. but I rarely have cramping and I feel good most of the time, no mood swings. No food cravings, is this normal? Please give some helpful advice so I can get some peace of mind, I’m a bit concerned and don’t want another miscarriage🙈
