I finished my period nearly 3 weeks ago and have since been having dark brown clotting with occasional pink/red in my discharge for 4 days. I am not currently using any birth control except for condoms with my partner of 7 years. Is this something to worry about.
Fibroids can cause extensive clotting. Menstrual blood has already clotted before coming out, so it tends to be old blood. Go to the doctor for a checkup.
