7w2d ultrasound

As I was getting ready to leave for doctor appointment, started red bleeding again. And again, panic set in. Why??????? Within an hour was in doctor's office sobbing. And, amazingly, ultrasound showed everything was just fine. All sizing was good. Even the spot that was showing as detached area with fluid last time, appeared to be gone. And, the best part....steady, strong heartbeat at 144bpm. (Acceptable range is 120-160). This baby is sure giving us a run for the money! And, of course, red bleeding has continued ever since the appointment, which doc says is expected.
