I've been having period like cramps on and off for the last couple weeks. Today unlike other days it's just be constant since 5AM (it's now 1:30pm.) The pain is constant so I cannot time them. The cramping is bellow my belly button and I'll get random lower back aches that I also cannot time. I called my nurse over an hour ago and had to leave a voicemail and still haven't gotten a call back. Little man really isn't moving much at all. I really only notice 2-4 movements in an hour... Just wondering if anyone else has experienced this and if so what did you do and should I be concerned? I'm 37+1.
