Early signs of pregnancy?

I'm due to start my period in 2 days. My husband and I had sex two of the three days I was ovulating according to Glow. I used to be one who rushed out and bout a test like a week before my period but no sense in wasting money lol all I know is that it's very unusual that I'm not cramping but I'm having to pee as much as I would if I took a water pill! Went to a movie last night. Had to get up in the middle of it, then go again after it, then again when I got home! Is excessive urinating a sign or pregnancy?
