I’m a first time mom. Currently 33 weeks and 4 days. I’ve been having really bad backache for the past week but only on my ride side. And started having pressure/pain in my pelvic area. Like when you have a heavy period and your vagina hurts type of pressure. So last night I started feeling cramping on my lower back/right side/lower abdomen. Not quite sure if that’s contractions cuz it was mild. Has anyone experienced this?
