I am 17 years old and masturbated 3 days ago.i have been spot bleeding ever since then once in a day. i have had my period 2 weeks ago(its regular) and i had never bled on masturbating before. do i have any issues or is it normal?and i have no pain?

Vaginal bleeding: Masturbatig is unlikely to cause vaginal or genital bleeding, unless you vigorously used some sort of object like a sex toy. Any and all new, abnormal, or unexplained vaginal bleeding requires professional evaluation. If you are sexually active (other than self-stimulation), at your age STDs are among the most common causes of spotting between periods. See a doctor about this ASAP. Good luck.
