Confused 😐

Hi girls. I’m 33 weeks pregnant and I went to my Dr. on Monday because I was having contractions he sent me to the hospital To get admitted. They did a sonogram and they told me my baby was measuring bigger they said that baby was measuring at 35+4 weeks and I was 32+4 on Monday according to my last period. They gave me some medicine to help my uterus relax and contractions kind of stop and they sent me back home that day. I started feeling the contractions again today. But I’m so confused about what they said. If my baby is measuring bigger is that a good thing if she decides to born before my due date?? Has anyone be in this situation before and delivered a healthy baby??
