Hello,
Get a pelvic examination and an ultrasound uterus done from a gynecologist to rule out any retained products of conception. It can be due to an incomplete miscarriage also.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Can someone please tell me am seeing mucus plug just yesterday I wiped and saw it on the tissue and I had a miscarriage 3 weeks ago am worried so badly
