First ultrasound is tomorrow at 8w3d, but it's at the hospital with a tech, not with my dr. Tonight, I've had light, but consistent cramping and lower back pain. Wiped 3 different occasions with brown spotting, but it's now stopped. Not cramping consistently anymore, but still feeling tugs. Should I call dr in AM, after ultrasound, in addition to telling the tech about it? I feel pretty scared, I gotta admit. Any other insights?
