I was treated for a UTI when I was 15 and then in Aril of this year at the age of 18 twice in one month. i'm now 19 and I'm 6 days late for my period, I've been a few days late before, I've been cramping for about a week now which I usually do, before I start my cycle. I also noticed an odor to my discharge a few weeks ago not fishy, but still a strong odor that was worse after sex. I have been experiencing nausea and have been tired which could be due to my diet and work schedule. In the last week I have been peeing more frequently, except not as much today. I've been having sharp pains near my hips, the same pains I experienced with my UTI.
