I was about to have. Nervous breakdown. No lie...
I have had a similar expreience but my Dr. explaine dto me that he was using small amounts of surgical tape to help stop the bleeding after the biopsy. Also, the substance that is applied to the cervix after the biopsy is high in iron whit causes the blood to clot, or form scabs. Becasue the cervics is so sensitive to abrasion it can bleed a lot. Once the cervix begins to heal, the blood that was absorbed by the iron containing matter is expelled from the body in large clumps that can be hard. Part of the "tissue" discharge is also skin that the body discards after being irritated by the vinegar solution used in the colposcopy. Gross, a bit scary but totally normal.
-I am not a Dr nor do I have any medical training. This information is based on my own personal experience. If you have heavy vaginal bleeding soaking through 1 pad in an hour or continual bleeding for longer than the length of your normal period. Consult your doctor.
I just read the above post and yes, this is very disturbing that the doc does not tell you any of this.
I thought i was passing bowel through my vagina as well.
I am about to have my period in a couple days so that should be VERY interesting!
