Almost 34 weeks & last night I went to triage because the cramping was horrible.. period like cramps. They basically went away almost 20 minutes after I got there so they didn't pick anything up on the monitors & said everything is fine. Today, no problems until about an hour ago & I have the same cramping,except it started in my back driving home from work. Laying in bed now & I feel like I'm on my period! Worst cramps ever! Should I go in again or is it nothing?? FTM & I don't know anything! :( please help
