am 6 weeks and 3 days pregnant with my second child. Last week, I went for an ultrasound and the doctor said I had a 5% separation and gave me medication to put in and take. Next week, I went back and there was no more separation at the top but a 15% separation at the bottom. I have absolutely no symptoms of bleeding or abdominal pain. So, doctor, can you tell me what is the cause of a 5% separation?
