Hello, I am having brown discharge, I am 7 weeks pregnant, I went to the doctor three days ago and they did a urine test, a pelvic check, a blood test, and also an ultrasound. Everything came back normal with a heart beat of 122/minute, but I have anxiety and am worrying now because I have skin like tissue, thin, easy to pull apart, not sticky, and not thick, when I wipe, is this normal clearing of old blood in the cervix or Is this something to be worried about?
