I'm 36.3 weeks pregnant, and since yesterday I've been having contractions. Yesterday I wasn't worried because while they did hurt, they stopped after a few hours and I just thought it was from being at work (I work on my feet all day). But again today at work I started getting them again and they hurt much worse than they did yesterday. I don't want to rush to the hospital just to be told I'm not in labor, but my Braxton hicks have never felt like this. Could it just be my body getting ready?
