UTI or Early Pregnancy Symptom?

Marie • Mama after infertility to three 💜💙💙
I'm 12 DPO and had a negative pregnancy test today. I had mild cramps 6-9 DPO. And since 10 DPO I have had frequent urination almost like the very early start of a UTI so I've been drinking cranberry juice. But it's day four... it's not better or worse. I don't have UTI pain... anyone have any ideas?? My period isn't due for two or three more days.
