I recently got mono. before symptoms appeared i noticed a change to my menstrual cycle. instead of a regular cycle i spotted dark brown for about 3 weeks instead of a regular one week. i started spotting dark brown again. is this normal with mono?

Mononucleosis doesn't usually cause vaginal discharge or bleeding; this may be just a coincidence. Any new or unexplained vaginal discharge or bleeding should be professionally evaluated, so get care soon. A potential connection is that mono can be acquired sexually, or by kissing during sex; and vaginal discharge is a common STD symptom. Good luck.
