Hello, I started my period, & it had always been normal, as it was this time. However, 1-2 days ago when I Shuld have been stopping, the bleeding has become non-stop w/ several clots from small to quarter size. Along w/ unbearable pain. This is day nine, & I m usually done after 5-6. Should I be concerned? I m 31 yrs old, 2 kids, & had my tubes tied 10 yrs ago.
