My period is now 8 days(usually 6-7). i've noticed bright red and brown clots when i wipe - no discharge. feeling movement on my right side (ovary?)

Do a pregnancy test: If you had a regular period it may be unlikely that your are pregnant. It is also too early to feel the movement of a fetus. Consider appointment with your OBY

Long period: At time there is variation, but that being said consider urine blood HCG. and if it does not resolve over 24 hours seek medical attention, may need sonogram.
