Odd period

So I just ended an odd period. I spotted for 5 days. Some days it was just light brown and only on the toilet paper, some days were light pink and kind of in the middle after that. I had 1 clot, size of a dime, cramps weren't bad but I was super exhausted, still am. I've never experienced a period like that before. Has anyone else been through this and ended up pregnant? If so, when did you test and what made you test? As of right now, I have a headache and could use a nap. Haha
