Could I be pregnant or do I have a UTI?

My last period was about 2 weeks ago and I didn't get it on time. It came 3 or 4 days after my previous period. So okay, here is my issue...I had my period. Cool. But after I was not on it anymore, I began to see a change in my stomach size. It looks a little bit more bloated than usual. My lower back and sides have been hurting a lot too; I feel more sore and I look more wider than usual, also my pee is a light green color. This sounds silly, but granted me having my period and all, is there a possibility that I could be pregnant? OR could I possibly have a UTI? I have yet to take a pregnancy test. But I think I will pick one up tomorrow and see what my results are. Any advice would be great. Thanks.

From your post, we know you are sexually active and you have erratic periods. Nothing more can be deduced. Get two pregnancy tests, of different brands, and do them exactly as the instructions tell you at least twelve hours apart.
