We went for a scheduled hospital visit today, we thought it was 40 weeks (although it's already 41 weeks exactly, according to all calculations from previous ultrasounds). Sent home, they said early, until 28 I can still give birth myself (waiting until 41 weeks 3 days or 4 days). Not too much? Almost 42 weeks. Before we thought it was early, then prematurity, now early again (they count differently, it's scary somehow).
