Period has been irregular. For 2 weeks now going from light bleeding to brown discharge. No pain. Sexual intercourse 8 months ago. This is everyday.

See below. Menstrual irregularities are not uncommon. Anovulatory cycles are one cause. If this irregularity persists for a month it would be time to see your doctor.
