Hi ladies, question for you.. it's only 4:49 am here and around 3:30 I woke up to my stomach tightening and cramping real bad then all of a sudden shoots through my back really bad. I'm (33w & 4d) pregnant. I could barley get up or even turn over without crying. When I got up to use the bathroom I felt so much pressure drop on my pelvic area. SUPER PAINFUL. The pain is still in my back currently now. What could this be? When I was pregnant with my daughter this didn't happen, she's (2) now. I'm currently pregnant with a boy now.
