I am two. Weeks late on my period, negative home pregnancy tests, noticed alittle blood after I wiped from urinating, symptoms of uti but they are slowly getting better, what could be wrong with me?

Hormonal imbalance. 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.
