Really bad back pain at 8 weeks

The past few nights I’ve been getting horrible lower back pain. During my ultrasound at 6w6d my midwife said I had a retroverted uterus (tilts back). She said it’s like being left handed, nothing to worry about. I asked if that’s why I had such bad backaches during my periods and she said yes. I know my uterus is supposed to be stretching but I haven’t even been cramping really, just sore breasts and nausea. This back pain is REALLY bad, I’m not 8 months, I’m 8 weeks! 😳 It’s hard to fall asleep at night, tonight is not going to be fun.

Anyone else?!
