What are the chances I am pregnant?

I started my period on April 2, on April 10th, 11th, 14th, and 15th my boyfriend and I had . I felt what I am almost positive was ovulation in the middle of the night on the 16th. Starting on 20th I had some light cramping, I woke in the middle of the night and had a few small twinges of sharp pain that went away. I since have had more mild cramping on and off and the small twinges of sharper pain. Also starting around the 20th I had like a white, think, milky like discharge. (sorry tmi). Then yesterday which would be one week before my period is due I had a really strong crampy twinge out of no where and when I went to the bathroom I had a pink discharge...not a whole lot just like a quarter size amount. I am still having the cramping. I know taking a pregnancy test is obviously ideal, it's just so hard to wait, because right now it wouldn't be accurate anyway.. Thanks in advance for your answers!
