Hello girls?

Hello girls ? I'm at 38 weeks on ultrasound but 36 according to my cycle. Which one is correct? Has anyone experienced this? As a first-time mom, I don't quite understand. My lower abdomen, bones, and waist are hurting. My belly sometimes hardens, and the baby doesn't move much at night, sometimes active. I try to walk more, but getting up and walking hurts. Are there any signs of labor? ? I want to start drinking raspberry leaf tea.
