I'm having clear vaginal mucus with blood in it for the past 3 days. Before having this I was spotting 1-2 days a week now for a month. Along with a 8day period the second week. What could this be from?

Could be pregnancy. If there is a chance that you could be pregnant, abnormal periods could be due to pregnancy. Anyways, see your dr. To determine.
GYN. I suggest a pelvic examination, pap smear , pregnancy exam, blood tests for thyroid function, and female hormonal levels. Your question requires further investigation. Call you gny for an appointment.
