Im 26, ttc for 15 months.i have a dark brown discharge 5-10 days before my period every month.sex is painful with blood. reason to be worried?

Not normal: Consistent pain with sex, and consistent bleeding with sex are not normal. Don't worry, but you'll want to be checked by a doctor if this persists.

See a gynecologist.: The symptoms sound like "mitteschmerz" a german term for midcycle pain of ovulation. The pain during sex maybe due to the sensitivity caused by the ovulation.To alleviate your worry, it is best to see a gynecologist.
