After 8 days of period, im still experiencing spotting and slight pain at right fallopian/ovary area. What is happening?

Test for pregnancy. This is obviously not normal for you and so i would recommend checking a pregnancy test. Infections such as pelvic inflammatory disease can cause such symptoms etc, or taking certain medication can change the quality/quantity/time of your period, so it is difficult to tell from your info. If pregnancy negative or postive..Consult doc for eval/treat/follow.. Good luck.
