8week midwife appointment

Ellie

So I had my first midwife appointment on Monday, they did the norm, urine test, bloods, carbon monoxide test etc. Asked a million questions about my medical history. Anyway since then I have been wondering how the midwife knows I’m actually pregnant? It’s like she just took my word for it. She said my urine was good, wasn’t dehydrated but other than that nothing. She didn’t even ask if I had any pregnancy symptoms. Is this normal?
