11 DPO, what do you think?

I’m about 11 DPO I believe. My period is due Sunday. Last night I went to the bathroom about 9PM and had about a quarter size of blood in my undies and when I wiped I had pinkish blood. I put a pad on and then there was just a little brown on the pad and barely anything when I wiped. Today, absolutely nothing. I’ve been crampy all day, very tired and felt like I had a UTI but only felt like that for a few hours. I’m praying I’m pregnant? What do U guys think of my symptoms? Anyone had anything similar?
