I am 39 weeks 3 days and I have been having mild contractions for about 5 hours now. Over the past 2 hours they have gotten stronger, about 20 mins apart and I am very nauseous and sweaty while I have them. They are also lasting over 30 seconds. Thw contractions have also moved from my upper stomach to lower with some mild cramping feeling. This is my second child but was induced with my first so this is all new to me ! Could this be the start of labor !?
