Maybe labor

So I think I'm having contractions like 10-15 min apart. Mild to moderate. My last appointment a week ago I was 2cm dilated and im 37 weeks now and have a repeat section scheduled May 9th. He's been measuring big for weeks though (don't have GD) and at 35.5 weeks he measured at weighing 7lb4oz already. Even tho we know those scans aren't always accurate. I keep second guessing myself wondering am I really having contractions? I don't want to go in to the hospital and they tell me I'm still 2cm with no other change and monitor reading very light contractions and they send me home. Opinions?
