Can anybody tell me if I could be pregnant?

My period started 2 wks ago today. Everything seemed normal, except the last few days of it there was brown blood, which for me doesn't usually start until the very end of it. Af few days after my period was gone I noticed light pink discharge. Only a little bit and only that one time, I figured it was left over from the period and din't think anything of it. Then a couple days after that I started cramping and my were sore. I figured maybe I was ovulating a little earlier than usual, but that started almost a week ago. At first the cramps were hardly noticable. Friday is the day I thought I would be ovualting and they were VERY strong and painful. The next few days were mild and today again they feel pretty strong. Not unbearable but very uncomfortable. I don't want to take a test until I am closer to my next expected period (around the 26th) becuase I figure it will probably come out negative. Besides the cramps and mildly sore s I am very tired, extremely forgetful and thoughtless, and yesterday I noticed everything tasted REALLY good. Has this ever happened to any of you? Please share any ideas of what else you think it could be. Thanks!
