37 weeks as of today, FTM. been feeling off all day. And tonight once i lay down my normal routine of BH starts but suddenly its different. My entire stomach is as hard as a rock and I guess right at my panty line it feels like a bruise being squished and a slight period cramp. New experience. Also getting nauseous with each one. I've had 5 in the past hour. My lower back and hips are also super sore suddenly. Should I be freaking out or is this just BH being extra???
