13weeks 4days

Okay so I'm 13w4d and we went and bought a few bits for the baby but I wasn't excited or emotional. Nothing. I just don't feel pregnant this is my second and I'm quite small where as on my first I already had a bump tbh. I don't know whether it's the hormones or whether it's normal to not feel pregnant 😔. I've had 2 scans so far I've been mesmerised but after them I go back to feeling like this!
