Pregnant or UTI

Kayla

My boyfriend came in me twice. Once on the day after my period almost two weeks ago and once a couple days ago, a day after my fertile window. Today, I have been urinating like crazy. I have peed at least 10-12 times today. Peed 5 times within nearly four hours. This is not normal. I took a pregnancy test yesterday and it came back negative, but it may be to early for it to detect any HCG. Help?
