So I’ve been having contractions on and off for the past couple of weeks but now when I have them I get this really bad cramping feeling. Almost like a really heavy period. I have an appointment with my high risk doctor today at 11 but has this happened to any of you ladies? Is it possible they could be turning into real contractions? I’m so worried she’s trying to come early. I had Sawyer exactly 3 weeks before my due date but my contractions didn’t hurt me at all. I was just uncomfortable 😑
