Thanks for the query,
In your case cause of bleeding is not irritation to fibroids.
Fibroids per se causes abnormal bleeding pattern.
Abnormal uterine bleeding
is the most common symptom of a fibroid.
If the tumors are near the uterine lining, or interfere with the blood flow to the lining, they can cause heavy periods
, painful periods, prolonged periods
or spotting between menses.
Fiboid can be treated successfully by drufs like GNRH analogs, myomectomy and emdolization.
Hope this helps.
