My cycle are running at 37 days. on day 35, it felt like they were stuck and needed piercing . only after intercourse did they start flowing immediately. however too thick to make it out to the sanitary towel. when i wipe its clots,heavy and thick.

Period:bleeding: In mid 30's, periods begin to change, because the ovaries require more stimulation to produce an egg at ovulation, which delays the onset of a period until 14 days have passed after ovulation. Bleeding is often heavier because the estrogen thickens the lining of the uterus, and clots sometimes occur, which temporarily block the passage of blood. Oral bcp's may decrease this.
