I feel like I'm spamming with all these questions but idk if I should go in now or wait till my appt in an hour. And idk if I should have hubby call into work. I'm just scared. I'm getting waves of really bad back pain every 4-5 minutes. Lasts 45-60 seconds. Stomach tightens with some of them but not always. It's a mild tightening. Plus now I'm getting really sharp pain in my vagina and lower abdomen along with it and baby isn't really moving like he normally does.
