Thanks. :) My UTI sign is pain in my kidneys, so I am pretty sure it's not that. Mostly I was just looking for anecdotal evidence that increased urination can begin as early as 7-10 dpo.
I found this on a medical website, so it does help confirm for me that I ovulated when I thought I did:
"Urinating more often is one of the very early signs of pregnancy. Many women experience more frequent urination even before a missed period, usually from about 7-12 days after the temperature rise at ovulation. The changes in hormone levels produced by implantation of the embryo, especially the hormone "human chorionic gonadotropin" (hCG), cause more frequent urination."
