Severe lower back pain 10-11DPO


Hi! I’m having severe lower back pain on my left side... to the point I cannot lay comfortably. I don’t usually get lower back pain before my period, it seems like a new symptom. My boobs feels like they are 20lbs a piece.... just enormous, heavy, and sore. Anyone have similar symptoms? Is this normal period symptoms or something I should be paying better attention to?
