Hard to explain..

Does anyone else have days where they don’t feel pregnant? I’m 16 weeks today. No bump. I’ve seen the ultrasounds, heard the heart beat, made the announcements. I’ve bought clothes, and bottles, and a stroller. I’ve hung the clothes, and discussed names with my husband. But some days when i think about my pregnancy it feels more like I’m planning for one. The clothes are for one day when I get pregnant. The names are for one day when we’ll need them. I know I’m pregnant, but it feels like I’m trying to convince myself I’m pregnant. I don’t know if anyone else has felt this way and if there really would be advice.
