Whats the chances of me having ovarian cancer or endometrial cancer. Pelvic pain & abnormal spotting on and off. 19, black, overweight, pcos?

Remote. You symptoms are very unlikely to be due to cancer. Hormonal imbalance is the likely explanation. Menstrual irregularities are not uncommon and anovulatory cycle is a common cause. If you miss more than two periods it would be time to see your doctor. If you do not wish to be pregnant, use contraception all the time. You may consider implanted contraceptive or an IUD.
